Effects of ground and satellite remote monitored air pollution and absolute humidity on daily unscheduled outpatient visits. In the analyses of AH-calibrated AOD and AH, season was used as a covariate; and in the analyses of AOD and PM10, absolute humidity and season was used as covariates. The analyses were limited on non-holiday/non-administrative interruption days, with 202 days for AH-calibrated AOD and AOD model analyses, and 269 days for PM10 and AH analyses. Due to small number of daily events resulted in unstable statistical estimations, we did not include the results for heart failure, heart rhythm disturbances, and peripheral vascular diseases. In all analyses, AH-calibrated AOD, AOD, PM10, and AH were log2-transformed for easy comparison.
