Conclusion  
Greater RRI, abdominal obesity, and greater BLS account for a lower GFR in NAFLD patients suggesting the hypothesis that inter-related factors can be operating early in the natural history of obesity-related kidney and liver disease.

this might be the reason i have creatinine increases from time to time even though within norml ranges and increased alt 30-48, i hope i got rid of this fatty liver by the decrease of bmi this month
