P values for unadjusted paired t tests comparing the two arms of the study are shown in the fifth column. Adjusted P values in the repeated measures analysis are shown in the sixth column. These P values were adjusted for age, years of education, WAIS-R, and baseline measure for that particular variable. Significant results are highlighted in bold. For the adjusted analyses, treatment test P values were examined initially. If the treatment test P value was more than 0.1, indicating no treatment-test interaction, it is not shown in the table, and only the overall treatment effect is shown. If the treatment test P value was 0.1 or less, indicating a possible treatment-test interaction, this value is listed in the table, and subsequent analyses were done for individual measures. A, Anxiety; BP, bodily pain; C, confusion; D, depression; F, fatigue; PF, physical functioning; RE, role emotional; RP, role physical; SF, social functioning; T, tension; V, vigor; VT, vitality.
Raw scores compared using an exact McNemar’s test because many values were at ceiling.
