Two assessors independently reviewed trials for relevance, extracted data, and assessed risk of bias using the Cochrane Risk of bias 2 tool.

In most trials, the intervention was bicarbonate. Risk of bias was assessed as moderate for most trials. In ICU patients with acute kidney injury, buffering therapy probably has no large effect on survival outcomes (low certainty), but likely reduces the use of renal replacement therapy and the rate of bloodstream infections (moderate certainty). Buffering therapy likely does not have an effect on survival outcomes in patients with out\u2010of\u2010hospital cardiac arrest (very low to low certainty).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Buffering therapy in ICU patients with acute kidney injury likely has beneficial effects on the use of renal replacement therapy, but probably no effect on survival outcomes.
