Models adjusted for all individual-level covariates. a) ≥2nd quartile: 1st quartile = referenced group, 2nd-4th quartile = treated group; b) ≥3rd quartile: 1st-2nd quartile = referenced group, 3rd-4th quartile = treated group; c) ≥4th quartile: 1st-3rd quartile = referenced group, 4th quartile = treated group; Significance levels: “*” p < 0.100, “**” p < 0.050, “***” p < 0.010.
