Fig. 3From: Association of meteorological factors and ambient air pollution on medical care utilization for urolithiasis: a population-based time-series studyLevels of selected meteorological factors and ambient air pollutants and the adjusted excess risk of medical care utilization for urolithiasis. Ureteral stones: (a) average temperature, (b) PM2.5, and (c) CO. Renal stones: (d) average temperature, (e) PM2.5, and (f) CO. PM2.5, particulate matter ≤2.5 μm; CO, carbon monoxide. The X-axis shows lag days. The Y-axis shows the percentage of adjusted excess risk with 95% confidence intervals. *p < 0.05Back to article page
