Figure 4 Index plots of the dfBETA (black dots) for the Cox regression of time-to-event on the age (A), height (B), sex (C), duration of catecholamine administration (D), duration of ICU stay (E), mechanical ventilation: sex interaction (F), time to regain consciousness (G), duration of pharmacological sedation (H), weight (I) and strength at first measurement (J). The dashed red horizontal line represents a value of 0 for dfBETA; the dashed blue line represents the locally-weighted scatterplot smoothing (LOWESS) fit. The residuals should remain centered around zero, indicating stable parameter estimation (RStudio, 2023.09.1, build 494, Integrated Development for R.
