Fig 2. Comparison of the plotted proportional meta-analysis, according to etiology in both cats and dogs, regardless treatment, for overall mortality.

Effect differences were seen due to the non-overlap of the 95% confidence intervals showing a higher rates of mortality in the AKI due to non-infectious (cats and dogs; and only dogs) compared with AKI due to infectious (cats and dogs; and only dogs), as their CIs did not overlap. However, there was no statistically significance difference between rates of mortality by etiology in only cats, as their CIs overlapped.
