Line Step from Scientific Research

Shows the cumulative proportion of patients in each treatment group with each value of number of days of organ support during the first 30 days following random allocation, with death listed last on the axis, corresponding to a value of 31. Curves that rise more steeply indicate a more favourable distribution in the number of days of organ support. The height of the curve at any point from 1 to 30 days indicates the proportion of patients with that number of days of organ support or fewer (eg, the height at day 20 indicates the proportion of patients that survived to 30 days with <=20 days of organ support). The height of the final step of each curve from 30 to 31 indicates the mortality on or before day 30 in each group.
