Fig. 2: Causal relationship of short sleep duration on lifespan.
From: Shared genetic architecture and causal relationship between sleep behaviors and lifespan

A Scatter plot of two sample MR results of short sleep duration on lifespan. The Slop of different colorful lines represent the estimated MR effect of different MR methods. B Forest plot of short sleep duration on lifespan. Each line indicates the effect of an IV. C Forest plot of leave-one-out result of short sleep duration on lifespan. Each line shows the result of IVW estimate of short sleep duration on lifespan after removing this SNP. No effect line crosses zero indicates the result is robust.
