Statistical methods / analysis
Individual patient data meta-analysis. Individual patient data from each eligible trial was pooled and all the outcomes were analyzed based on the intention to treat principle, taking all randomized participants into consideration. The effect of different dialysis dosing intensities upon mortality and dialysis outcomes was analyzed using log-binomial regression with a random effects model and random study-by-treatment interaction.

Summary
Brief summary
Renal replacement (RRT) dose intensity may affect patient and kidney outcomes in severe acute kidney injury (AKI) but randomized controlled trial (RCTs) have been contradictory for mortality and inadequately powered for renal outcomes. The Investigation, Management, Prognosis, Recovery, Observation, Value and Evaluation of Acute Kidney Injury (IMPROVE-AKI) collaboration brings together investigators from current randomised clinical trials of RRT dose intensity in AKI to perform IPDMA of the effects of RRT dose intensity.
