Forest plot for the meta-analysis on the effects of low-dose dopamine compared with placebo or no therapy (data provided by J. Friedrich). Subscripts T and C correspond to the arms with/without dopamine. DL was used in estimating the between-study variance. The studies reported urine output in a variety of units. For example, Baldwin 1994 used mL/kg, Sprung 2000 used mL/h, Cregg 1999 used ml/kg/h, and O’Hara 2002 used ml/24h
