Hi all,
I would like to get a hint in the easiest way to analyse this data, am not very good in STATA and more so with Biostatistics.
I have a data set with data from an anti-malarial study with 3 arms placebo(SP), and two active arms, (SP+AS3) and (SP+AS2).
gametocytes count is measured at days 0,1,2,7,14,21 and 28
The dataset is presented in a wide format
am intrested in effectiveness of treatment on gametocytes count and its prevalence during the 28 days
1. How do i calculate odds ratio and proportions and 2. p values of (SP vs AS1) and (SP vs AS2) and
3. Corresponding p values of difference in the prevalence in those two groups with their respective 95% confidence intervals for the days above.
Do I need to change the data set to a long format or I can do all this analysis with the current wide format.
Thanks
Liwindi
