From: Association of short-term exposure to ambient carbon monoxide with hospital admissions in China
Percentage change (PC) with 95% confidence interval (CI) in hospital admissions associated with 1 mg/m3 increase in daily carbon monoxide concentrations based on the subset of data only including days with concentrations below the specified values specified on the X-axis. The numbers in second column indicate the percent of days used in each threshold analysis, on average across the cities, compared to the data used in the non-threshold analysis.
