Thirty-day mortality as a function of admission plasma proenkephalin A 119–159 (penKid) concentration in the subgroups sepsis, cardiac arrest and trauma. The vertical line at penKid 80 pmol/L is the upper normal (99th percentile) limit. The continuous lines represent smoothed averages, i.e. the average 30-day mortality in a small neighbourhood of a penKid value. The coloured bands around the smoothed averages indicate 95% confidence bands. Individual patients are represented by dots with jitter added. Thus, y values in the interval (− 0.1, 0.1) represent survivors (0 with added jitter), and y values in the interval (0.9,1.1) represent non-survivors (1 with added jitter)
