Figure 3.

Figure 3 includes 3 graphs. First graph plots cumulative exposure in crude model, ranging from 1.044 (1.017 to 1.071), 1, 1.12(1.02 to 1.24), 1.23(1.17 to1.42), less than 0.001, 0.34(0.09 to 1.43), 1, 1.11(0.99 to 1.24), 1.12(0.92 to 1.37), and 0.059 (y-axis) across adjusted HR (95 percent CI), ranging from 0.80 to 1.25 in increments of 0.45 (x-axis) for PM subscript 2.5, events, and participants. Second graph plots cumulative exposure in adjusted model, ranging 1.051 (1.023 to 1.079), 1, 1.20 (1.09 to 1.33), 1.27 (1.15 to 1.41), 1.21 (1.09 to 1.34), less than 0.001, 0.50 (0.12 to 2.00), 1, 1.20 (1.90 to 1.34), 1.28 (1.04 to 1.59), and less than 0.001 (y-axis) across adjusted HR (95 percent CI), ranging from 0.80 to 1.25 in increments of 0.45 (x-axis) PM subscript 2.5, events, and participants. Third graph plots exposure prior 3 years in adjusted model, ranging 1.033 (1.007 to 1.058), 1, 1.09 (0.99 to 1.20), 1.17 (1.06 to 1.30), 1.11 (1.01 to 1.23), 0.015, 0.83 (0.31 to 2.23), 1, 1.18 (1.06 to 1.29), 1.31 (1.06 to 1.62), and less than 0.001 (y-axis) across adjusted HR (95 percent CI) ranging from 0.80 to 1.25 in increments of 0.45 (x-axis) PM subscript 2.5, events, and participants.

The association of particulate matter with aerodynamic diameter ≤2.5μm (PM2.5) and poor cognitive function [Mini-Mental State Examination (MMSE) score<18] in competing risk models among Chinese older adults 65 years of age and older. Adjusted covariates include age (continuous), sex, residence, current marital status, living pattern, education (literacy status), smoking status, alcohol drinking status, regular exercise, diabetes, heart disease, hypertension, respiratory disease, disability in activities of daily living, gross domestic product (GDP), physicians per z persons at prefecture level. Note: CI, confidence interval; HR, hazard ratio.
