What is the quality of the evidence for the ACE inhibitor relative effect on all-cause mortality in CKD stages 3-4?
The quality of the evidence for the ACE inhibitor relative effect on all-cause mortality in CKD stages 3-4 is VERY LOW due to risk of bias, imprecision (from 86 fewer to 18 more). This is downgraded by 2 increments if the majority of the evidence was at very high risk of bias.
