Sex specific relationship between polygenic score (PS) and spirometry results. Boxplots of median and interquartile range (IQR) FEV1 (A) or FEV1/FVC (B) z-score by PS group (defined by PS z-score above or below 1). Whiskers extend to 1.5 times the IQR, datapoints outside this range are shown as points. P-value reported here was calculated using a two-sided t-test. Please refer to text for P-value from regression model adjusting for age and self-reported race as confounders.
