Extended Data Fig. 6 ∣. Power analysis.
Boxplots (center, median; box, interquartile range; whiskers, 1.5 * interquartile range or the most extreme data point) show the calculated power for associating the 40 SNPs with BMI, given the effect size observed in our cohort and various effective sample sizes (N). Alpha was set to 3.9 × 10−9 based on a cutoff of 0.05 and a Bonferroni correction for 12,686,191 hypotheses.
