The random effects model was used. b Meta-regression for the effect of the difference in calories between the lower and higher caloric intake groups in each trial on incident renal replacement therapy. c Meta-regression for the effect of the caloric dose in the lower caloric intake group in each trial on incident renal replacement therapy. d Funnel plot for the corresponding studies
