From: Causal relationship between endometriosis with infertility and ankylosing spondylitis
Scatter and forest plot of the association of endometriosis of pelvic peritoneal with the risk of AS. (A) Forest plot: dots and lines indicate causal estimates of pelvic peritoneal endometriosis on the risk of AS. (B) Scatter plot: each black dot represents an IVs plotted from the IVs estimate on the pelvic peritoneal endometriosis sign and the IVs estimate on the risk of AS by the standard error bars. The slope of the line corresponds to the causal estimate using each of the different methods.
