1. Proportion of missingness, p: 1%, 5%, 20%, 35% of participant-days missing exposure value 2. Types of missingness: a. Missing Completely at Random (MCAR): p% of the participant-days/assessments in each of the 1000 simulated datasets were removed completely at random. b. Missing at Random (MAR): MAR mechanism was simulated under a logistic regression model as a function of an auxiliary variable, the SOFA score, with varying correlations with missingness: \( logit\ \left({missing}_{ij}\right)=\alpha +{\beta}_{SOFA_{ij}}\ast {SOFA}_{ij} \), where \( {\beta}_{SOFA_{ij}} \) = 0.01, 0.1 and 0.2 representing weak, moderate and strong relationships with missingness. Here α was manipulated for different combinations of \( {\beta}_{SOFA_{ij}} \) to generate the required proportion of missingness p. c. Missing Not at Random (MNAR): MNAR mechanism was generated under a logistic regression model with the probability of missingness having a weak, moderate, and strong association with the daily delirium status. logit(missingij) = α + βdel _ miss ∗ deliriumij, where βdel _ miss took on values 0.1, 0.5 and 1.0 representing weak, moderate and strong relationships with missingness. Here α was manipulated for different combinations of βdel _ miss to generate the required proportion of missingness p. |
