Histograms for hourly-adjusted UO. We can universally see a bimodal, smooth, and homogenous distribution with a positive skew and no significant outliers, suggesting natural variability in the study population without extreme values, data entry errors, or distinct sub-populations. In panel d we can see a similar pattern, but without smoothing due to weight being grouped in 10 kg intervals in the AUMCdb. Panel (a) shows the hourly-adjusted UO plotted for MIMICdb (N = 5,211,377); Panel (b) shows the hourly-adjusted UO plotted for AUMCdb (N = 2,140,972); Panel (c) shows the hourly-adjusted UO per kg plotted for MIMICdb (N = 5,119,874); Panel (d) shows the hourly-adjusted UO per kg plotted for AUMCdb (N = 2,063,720). L left, R right, UO urine output.
