From: Causal relationship between endometriosis with infertility and ankylosing spondylitis
Scatter and forest plot of the association of endometriosis of rectovaginal with the risk of AS. (A) Forest plot: dots and lines indicate causal estimates of rectovaginal endometriosis on the risk of AS. (B) Scatter plot: each black dot represents an IVs plotted from the IVs estimate on the rectovaginal 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.
