Hi,
I have just started understanding and usung stata, and having used SPSS- I am fumbling a lot.
I have a gender matched dataset for ADHD vs non-ADHD kids. I matched on gender because the analysis required was simple correlations and associations using chi square/fisher's exact and t-tests and gender was significantly different among the two groups. The ADHD sample is N=23 only while non-adhd N=248 which makes a multivariate analysis a little difficult.
I want to look at certain physiological and pulmonary outcomes among these two groups. The study is not case control either.
I have read an article on BMJ, stating that matched analysis is not mandatory after matching and that standard analysis can also be performed. (http://www.bmj.com/content/352/bmj.i969)
Therefore, I went ahead and performed the standard required analysis.
However, now I am double minded whether that was the best approach and whether matched analysis is the right way to proceed.
I am new to stata, I have been meaning to learn it and I believe this can be a start.
Can you please guide me which commands to use to run t-tests, chi squares/fisher exact, and correlations for matched data?
