FIGURE 3.

Genome-wide genetic correlation between three lung function traits and three obesity traits in the a) China Kadoorie Biobank (CKB) and b) UK Biobank (UKB) cohorts. FEV₁: forced expiratory volume in 1 s; FVC: forced vital capacity; BMI: body mass index; WHRadjBMI: BMI-adjusted waist-to-hip ratio; WCadjBMI: BMI-adjusted waist circumference. The colour of each box scales with the magnitude of the genetic correlation (R_g). *: pairs of traits with nominal significant genetic correlation (p<0.05); **: pairs of traits with significant genetic correlation after correcting for multiple testing (p<0.05/9). Boxes without labelling are trait pairs with nonsignificant genetic correlation.
