STATISTICAL ANALYSES Both parametric and non parametric tests will be carried out. Initially data will be examined for errors in input. The analysis will be carried out on intention to treat basis using SPSS version 16.0. Initial analyses to compare the two groups were carried out using t test and χ2 test. A linear regression analysis will be used, with end of therapy as the dependent variable and group allocation, as independent variable. In order to see the effect of baseline differences in pre treatment scores on effect of therapy a second analysis was carried out with baseline scores entered as independent variables in addition to treatment groups (i.e., dependent variable post treatment scores, independent variable treatment group and pre treatment scores).
