Fig. 6From: A data-adaptive method for investigating effect heterogeneity with high-dimensional covariates in Mendelian randomizationStratum-specific estimates (error bars represent \(95\%\) confidence intervals) for the effect of BMI on lung function in deciles of the population stratified on covariates using the doubly-ranked method. The Q statistic is a measure of heterogeneity in the stratum-specific estimates. Confidence intervals are not corrected for multiple testingBack to article page
