| Nov 29, 2022 at 18:14 | comment | added | Matthew Raifman | @Noah Thanks, yes standard deviation. Sorry, I should have specified. The epidemiological study is a meta-analysis of pooled relative risks so I think the SD is the distribution of RR from studies that reported RR at each exposure point. I suppose therefore the n may equal the number of studies rather than population? Then again, in a meta-analysis each study is weighted by random effects so perhaps the overall mean/CI reflects the full population? Have you ever seen anything like this? Here's a link to the study FWIW. ijbnpa.biomedcentral.com/articles/10.1186/… | |
| Nov 29, 2022 at 17:55 | comment | added | Noah | When you say "SD", I assume you mean standard deviation, but standard deviation of what? Do you mean the standard error of the estimate of the RR? Also, symmetric confidence intervals are quite unusual for RRs; do you know how these were obtained? | |
