Fig. 1: Hazard ratios (95% CIs) for mortality by cause-specific diseases, linked to per 10 μg/m3 increase in NOx.
From: Associations of long-term exposure to nitrogen oxides with all-cause and cause-specific mortality
Time-varying Cox regression was used to assess the associations between NOx and mortality, with the adjustment of age, sex, ethnicity, body mass index, education, occupation, smoking status, alcohol consumption, physical activity, residential area, and household income. Dots represent the estimated hazards ratios for mortality risk associated with per 10 μg/m3 increase in NOx, and horizontal lines denote corresponding 95% confidence intervals. Two-sided P values less than 0.05 were considered as statistically significant. Asterisk (*) denotes P < 0.05. Source data for Fig. 1 are provided as Source Data 1.
