Posterior mean and 95% posterior interval of the PM_2.5-coefficients under various baseline risk models^†

Baseline hazard	Cumulative estimate (95% posterior interval)	4-week lag estimate (95% posterior interval)
Non-spatial	1.067 (1.020, 1.116)	1.023 (0.961, 1.087)
Spatial frailty	1.069 (1.020, 1.248)	1.017 (0.956, 1.074)
Space–time interaction	1.073 (1.025, 1.117)	1.031 (0.977, 1.088)

^†The estimates are presented as approximate relative risks (1.927β_j) per interquartile range (1.37 μg m⁻³ for total cumulative and 4.56 μg m⁻³ for 4-week lag).
