GRADE Working Group grades of evidence
High quality: we are very confident that the true effect lies close to that of the estimate of the effect
Moderate quality: we are moderately confident in the effect estimate: The true effect is likely to be close to the estimate of the effect, but there is a possibility that it is substantially different
Low quality: our confidence in the effect estimate is limited: The true effect may be substantially different from the estimate of the effect
Very low quality: We have very little confidence in the effect estimate: The true effect is likely to be substantially different from the estimate of effect

1 Serious risk of bias: studies that carry large weight for the overall effect estimate rated as high risk of bias due to lack of blinding and selective reporting.
2 Serious imprecision: wide confidence interval including both clinically relevant benefit as well as harm.
3 Serious inconsistency: differing ratio of drugs between subgroups of one study.
4 Upgrade due to dose‐response gradient: observed for both drugs. Effects therefore depending on ratio of drugs used in comparisons.
5 A sensitivity analysis without the results from four studies which were calculated according to Wan 2014 showed similar results.
6 Serious imprecision: Wide confidence interval, including less discontinuations with deferoxamine treatment.
7 Serious indirectness: Surrogate of creatinine used for patient‐important outcome of kidney failure.
