Figure 2
Stability paths of the elastic net regression for all-cause (a), cardiovascular (b), and infection-associated mortality (c). Each curve represents either a nominal predictor or a group (top/bottom quintile) of an ordinal/continuous predictor. The colors are coded as indicated. Vertical dashed lines represent the penalty parameter (ln-lambda) chosen by the stability selection, horizontal dashed lines represent the predefined selection threshold of 60%. Variables above this threshold at the selected penalty were considered stable. "High" and "low" indicates that the value falls within the top or bottom quintile of the total study population (see “Methods”).
