Table 1 Baseline clinical data for the study group and the historic control group. The historic control group (n = 86) was matched from a cohort consisting of 310 CRRT patients at Skåne University Hospital, Lund, Sweden and was not originally designed for this study and therefore some data is missing.
From: Modern CRRT systems are associated with lower risk of hypothermia
