Does the effect of staying in school until age 16 depend on the BMI PGS? Bars show 2SLS point estimates of effect of staying in school until age 16 on binary measures of the body size index (A), lung function index (B), blood pressure index (C), and summary index (D) for the bottom, middle, and top terciles of the BMI PGS distribution. Bars are centered at the median PGS value in the tercile. Brackets show 95% confidence intervals. Sloped lines plot β₁PGS_i + β₂. P corresponds to the P value of H₀:β₁ = 0.
