Imputation strategies for missing baseline neurological assessment covariates after traumatic brain injury: A CENTER-TBI study
Fig 6
Comparison of pooled proportional odds regressions for 6 month GOSE for fully imputed time points.
The ‘presenting’ ED arrival time point was a composite formed from the ‘referring’ and ‘study hospital’ ED time points to reflect the first contact with the ED irrespective of whether the patient underwent secondary transfer. The boxes/whiskers reflect the variability from the 200 imputed data sets used. Data shown for all strata (data for the ICU stratum was similar and is presented in the S6 Fig).
