Line Plot from Scientific Research

Ischaemic heart disease. Solid lines represent HRs, and the shaded areas represent 95% CIs. Curves within the 95th percentile of farming activity level in each stratum are shown. The models were adjusted for sex, age, education, household income, seasonal work pattern of farm, smoking status, alcohol consumption, consumption of fresh vegetables, fresh fruits, and red meat, leisure sedentary time, fuel types for cooking and heating in baseline house, cumulative exposure time to solid fuels in the past three houses, stove ventilation in the baseline house, duration of living with a smoker, exposure to second-hand smoke, BMI, waist–hip ratio, self-rated health status, hypertension and diabetes, family histories of heart disease and stroke, and the remaining activity amount after deducting farming activity from the total physical activity (MET-h/day). HR=hazard ratio. MET=metabolic equivalent of task.
