Question

A randomized trial was conducted to evaluate the safety of a new psychotic medication

one of the outcomes was whether or not a partipant in this study developed hypertension, measured as the average values of three blood pressures taken at each of the subsequeht clinic visits. all participantd were free of hypertension at the start of the study and randomized to receive either the new medication or the standard antipsychotic medication. Participants were followed for a maximum of five years for the development of hypertension

compute the relative risk of hypertension and participants receiving the new medication as compared to those receiving the standard and I psychotic medication. Compare the odds ratio of hypertension and patients receiving the new medication compared to those receiving standard medication. What is the cumulative incidence of hypertension across both groups.

Answer 1

Medication
	1	2
Hypertension Relative Ratio Odd Ratio	a [a/(a+b)]/c/(c+d) (a/b)/(c/d)	b [b/(a+b)]/[d/(c+d)]
Standard Pyschotic medication Odd Ratio	c c/(c+d)/[a/(a+b)] (c/d)/(a/b)	d d/(c+d)/b/[(a+b)]
