Relative risk of adverse events is shown using the length of stay variable definition for TKA: LOS > 0 (inpatient) relative to LOS = 0 (outpatient). Adverse events are listed at the left. Diamonds central to the horizontal lines indicate relative risks. Horizontal lines denote the 98.75% CIs of those relative risks per Bonferroni’s correction. The vertical line indicates a relative risk of 1. Therefore, horizontal lines that cross the vertical line indicate relative risks that are not statistically significant. Black lines and bolding indicate relative risks that are statistically significant.
