Incidence rate of NAFLD of different groups.

Group	Number	Number of NAFLD	Cumulative incidence (95% CI)	Per 10000 person-years
Total	9756	844	8.65 (8.10-9.20)	313.45

High Cr/BW ratio	4902	366	7.47 (6.65-7.98)	280.69
value	—	—	0.039	—
Nonelderly	8401	719	8.56 (8.01-9.11)	310.09
Low Cr/BW ratio	4262	422	9.90 (9.32-10.49)	347.42
High Cr/BW ratio	4139	297	7.18 (6.67-7.68)	268.75
value	—	—	0.008	—
Elderly	1355	125	9.23 (8.66-9.79)	337.92
Low Cr/BW ratio	592	56	9.46 (8.89-10.03)	325.07
High Cr/BW ratio	763	69	9.04 (8.48-9.61)	349.16
value	—	—	0.311	—

Note: participants were assigned into the high Cr/BW ratio (>1.32) group and low Cr/BW (≤1.32) ratio group. The nonelderly participants were <60 years old, while elderly participants were ≥60 years old. Abbreviations: CI = confidence interval; Cr/BW = serum creatinine/body weight; NAFLD = nonalcoholic fatty liver disease.
