I need to calculate the pooled odds ratio and associated 95% confidence interval for meta-analysis of 2 studies about the risk of bleeding. The only information I have is the odds ratios and 95% confidence intervals. They are 2.7 (1.8 – 4.0) in the first, and 1.3 (0.5 – 3.4) in the second study.
I computed the standard errors, weights, and pooled SE, OR and CI from the available ORs and CIs. According to my calculations, the standard errors are 0.204 in the first, and 0.489 in the second study, which gives the pooled OR and CI of 2.49 (1.72 – 3.60).
I’m not sure about this and I would appreciate if someone checks this up.
Thanks in advance!
