REGRESSION
An online double‐blind randomised controlled trial was conducted. Palliative doctors, nurses and other types of healthcare professionals were randomised into study arms differing by perceived source of advice (algorithm or another clinician). In fact, the advice was the same in both arms (emanating from the PiPS‐B14 prognostic model). Each participant reviewed five patient summaries. For each summary, participants: (1) provided an initial probability estimate of two‐week survival (0% ‘certain death’—100% ‘certain survival’); (2) received advice (another estimate); (3) provided a final estimate. Weight of Advice (WOA) was calculated for each summary (0 ‘100% advice discounting’ – 1 ‘0% discounting’) and multilevel linear regression analyses were conducted.Clinical trial registration number: NCT04568629.
