Fig. 2

Granger causality graph of the number of medical care utilization for urolithiasis cases and the related MFAPs in Korea: (a) ureteral and (b) renal stones. The figure shows the direct unilateral and bilateral relationships between urolithiasis and MFAPs. The X- and Y-axes represent the effects and causes, respectively. Therefore, the CO along the Y-axis indicates a cause that can predict the daily urolithiasis medical care utilization. MFAPs, meteorological factors and ambient air pollutants; CO, carbon monoxide
