In this way, a number of surgical procedures can be performed without the need for laryngectomy Surgery to remove part or all of a large surgical incision. The surgeon performs a tracheostomy, creating an opening in the front of the neck laparotomy An operation to open the abdomen.

The surgeon removes only part of cers, for example lung cancers, in which the abnor- the larynx (voice box)—just one vocal cord, just mal cells are particularly large. After a brief recovery period, the tracheostomy tube is removed, and the stoma closes up. In some cases, however, the voice may be hoarse or laryngeal Having to do with the larynx (voice box). It is said to be recurrent because it returns in its course to laryngitis An inflammation of the larynx. The voice changes may persist laryngeal palsy Paralysis of the larynx (voice after the fever and other symptoms of acute infection box) that is caused by damage to the recurrent have resolved. Laryngitis can also occur as a result of laryngeal nerve, which supplies the larynx (voice irritation to the vocal cords. People such as singers, box), or its parent nerve, the vagus nerve, which cheerleaders, or even small children after bouts of originates in the brain stem and runs down to the screaming may find that they become hoarse or colon.

When a cent-shaped cartilage pad in the outer portion of the person exhales, the air goes the other way. The vocal joint formed by the femur (thigh bone) and the tibia cords are relaxed during breathing, and air moves (shin bone). The lateral meniscus acts as a smooth through the space between them without making surface for the joint to move on. The vocal cords tighten up and move cus is toward the outer side of the knee joint. Air from the lungs is serves to evenly load the surface during weight- forced between them and makes them vibrate, pro- bearing, and also aids in disbursing joint fluid for ducing the sound of a voice.

In linear regression divalproex 500 mg generic medications you cant donate blood, the values of the outcome variables are predicted form one or more explanatory variables (see Chapter 7) order divalproex 250mg with amex symptoms melanoma. In logistic regression 250 mg divalproex with mastercard treatment for vertigo, since the outcome is binary, the probability of the outcome occurring is calculated based on the given values of the explanatory variables. Logistic regression is similar to the linear regression in that a regression equation can be used to predict the probability of an outcome occurring. However, the logistic regression equation is expressed in logarithmic terms (or logits) and therefore regression coefﬁ- cients must be converted to be interpreted. Although the explanatory variables or predictors in the model can be continuous or categorical variables, logistic regression is best suited to measure the effects of exposures or explanatory variables that are binary variables. Continuous variables can be included but logistic regression will produce an estimate of risk for each unit of measurement. Thus, the assumption that the risk effect is linear over each unit of the variable must be met and the relationship should not be curved or have a threshold value over which the effect occurs. Logistic regres- sion is not suitable for matched or paired data or for repeated measures because the measurements are not independent – in these situations, conditional logistic regression is used. In addition, variables that are alternative outcome variables because they are on the same pathway of development as the outcome variable must not be included as independent risk factors. A large sample size is usually required to support a reliable binary logistic regression model because a cell is generated for each unit of the variable. If three variables each with two levels are included in the analysis, for example, an outcome and two explanatory variables, the number of cells in the model will be 2 × 2 × 2, or eight cells. As with chi-square analyses, a general rule of thumb is that the number of cases in any one cell should be at least 10. When there are empty cells or cells with a small number of cases, estimates of risk can become unstable and unreliable. Using this method, variables are added to the model one at a time in order of the magnitude of the chi-square association, starting with the largest estimate. At each step, changes to the model can be examined to assess multicollinearity and instability in the model. If an a priori decision is made to include known confounders, these can be entered ﬁrst into the logistic regression and the model built up from there. Alternatively, Risk statistics 301 confounders can be entered at the end of the model building sequence and only retained in the model if they change the size of the coefﬁcients of the variables already in the model by more than 10%. At each step of adding a variable to the model, it is important to compare the P values, the standard errors and the odds ratios in the model from Block 1 of 1 with the values from the second model in Block 2 of 2. A standard error that increases by an impor- tant amount, say by more than 10% when another variable is added to the model, is an indication that the model has become less precise. In this situation, the model is less stable as a result of two or more variables having some degree of multicollinear- ity and thus sharing variation. This indicates that the variable added to the model is a good predictor of the outcome and explains some of the variance. As with any multivariate model, the decision of which variable to remove or maintain is based on biological plausibility for the effect and decisions about the variables that can be measured with most accuracy. All people with the disease are 56 years and older and all people aged less than 56 do not have the disease. Therefore, age group 3 predicts the presence of the disease and the age groups of 1 and 2 predict the absence of the disease. Here, the outcome groups (presence or absence of a disease) can be separated by the explanatory variable. Complete separation results in large standard errors as a result of overﬁtting the regression model. The Cox and Snell R square is similar to the multiple correlation coefﬁcient in linear regression and measures the strength of the association. This coefﬁcient which takes sample size into consideration is based on log likelihoods and cannot reach its maximum value of 1. Consequently, the Nagelkerke R square is generally higher than Cox’s and has values that range between 0 and 1. To evaluate the contribution of an explanatory variable to the model, the Wald statis- tic can be used. This statistic has a chi-square distribution and is the result of dividing the B value by its standard error and then squaring the result. This value is used to cal- culate the signiﬁcance (P) value for each factor in the model. In logistic regression, the constant is used in the prediction of probabilities but does not have a practical interpre- tation. It should be noted that when the absolute value of the B coefﬁcient is large, the standard error increases which results in the Wald statistic being underestimated. In this case, other methods such as a sequential method of entering variables should be used to assess the contribution of the variable to the model. In this model, the comparison model is no predictors, with only the constant (intercept) included.
