HRs are adjusted for age, sex, height, socioeconomic status, region and survey year. The reference category (HR=1) is the highest quartile (Q4) for zFVC and the lowest quartile (Q1) for SBP and BMI. Whiskers represent the 95% CI for each HR. Data included in online su pplementary e-table 7. BMI, body mass index; FVC, forced vital capacity; HSE, Health Survey for England; SBP, systolic blood pressure; SHS, Scottish Health Survey; z, z-score.
