 Associations between hourly personal‐level environmental temperature (PET) values and systolic blood pressure (SBP). The associations between systolic BP and each hourly (h) PET value measured during the preceding 24 hours. For example, lag hour 0=period from 0 to 60 minutes before CV outcomes were measured. Lag hour 10=period from 10 to 11 hours beforehand. Since BP was measured in most patients at a time between 5 pm and 7 pm, this means lag hour 10 corresponds to a 1‐hour period beginning from 6 am to 8 am and ending from 7 am to 9 am. Lag hour 15 corresponds to a 1‐hour period beginning from 1 am to 3 am and ending from 2 am to 4 am. Points indicate linear PET‐BP associations (coefficient β₁, change in BP per 1°C) and vertical line segments are the 95% confidence intervals for each hourly time point from the full (multivariate) linear mixed model (1). Statistically significant time points are bolded in square shape for P<.01 and in diamond shape for P<.05.
