Estimates based on N=365 HIV-infected men.
This table shows the difference in the mean level of GFR across time associated with various risk factors for kidney dysfunction as well as the change in the mean eGFR slope comparing those with an increase in total cholesterol of at least 50 mg/dl to those with an increase of less than 50 mg/dl over approximately a 3-year period following ART initiation.
