Fig. 3From: Incorporating repeated measurements into prediction models in the critical care setting: a framework, systematic review and meta-analysisAnnual number of studies with repeated measurements. This Figure shows the annual number of studies with reported measurements in the critical care setting. Figure a depicts annual averages of all studies and Figure b depicts annual averages of the studies per type of analysis performed, in which single-timepoint studies do not incorporate the repeated measurements, univariable studies incorporate just one repeatedly measured variable and the included studies incorporate repeated measurements of multiple variablesBack to article page
