Exposure to BTEX has been suggested to be a potential risk factor for asthma,[[1], [3]] a heterogeneous disease with unclear etiology, but its individual risk for adult asthma and its phenotypic clusters remains unclear. An hourly grid-scale model was utilized to estimate the residence-based ambient air BTEX levels and the time-lag effect (lag-0, lag-1, lag-2, lag-3, lag-4, and lag-5) on the daily asthma ERVs and outpatient visits.
