Estimated exposure–response curves for short-term exposures to PM2.5. Note: a Exposure-repose curve showing the RR increase in VAP with increasing PM2.5 concentration. Gray area indicates 95% CIs. b Cumulative-repose curve showing the cumulative effect of 10 μg/m3 and 30 μg/m3 increment of PM2.5 on VAP with increasing number of lags days. Lag 0-day is the VAP diagnosis day, lag 01-day indicate the period between VAP diagnosis and 1 day prior, lag 02-day indicate the period between VAP diagnosis and 2 days prior, etc., up to 7 days prior. PM2.5: Fine particulate matter; VAP: ventilator-associated pneumonia
