Table 2 Statistical analyses for each outcome measure

From: The effectiveness of telemedicine for paediatric retrieval consultations: rationale and study design for a pragmatic multicentre randomised controlled trial

Outcome measure Statistical Method
P1 Stabilisation time1 Linear regression with stabilisation time as the outcome, type of consultation as the main effect and PIM3 score as a co-variable
S1 Change in patient’s physiological status Linear mixed effects model with physiological status as outcome, type of consultation and time as main effects, and a consultation-by-time interaction term.
S2 Change in diagnosis Logistic mixed effects model with diagnosis as outcome, type of consultation and time as main effects, and a consultation-by-time interaction term.
S3 Destination of retrieved patients Logistic regression with destination as outcome and type of consultation as the main effect.
S4 Retrieval decision Logistic regression with retrieval decision as outcome and type of consultation as the main effect.
S5 PICU LoS1 Linear regression with LoS as the outcome, and type of consultation as the main effect.
  1. 1Data relating to stabilisation time and PICU LoS will transformed if necessary to meet assumptions of regression model.
