Duration of PPI Use and Risk of Renal Outcomes
We evaluated the association between duration of exposure and risk of renal outcomes among new users of PPI (n=173,321). Compared with those ex- posed for #30 days, there was a graded as- sociation between duration of exposure and risk of renal outcomes among those exposed for 31–90, 91–180, 181–360, and 361–720 days (Figure 2, Table 4).
