Descriptive data, before and after intervention, are expressed as Means ± SD; absolute difference (end-of-study minus baseline values);
p values obtained by comparing means in the variable values within each group, using t test for paired data;
p values obtained by comparing differences in the variable values between the two groups, using Student t test
