#The baseline characteristics that are associated with missingness at 2.5 year follow-up are highlighted in gray with ∧ indicating the variables that are associated with higher odds of missingness at 2.5 year follow-up. For categorical variables, the reference category was taken as the first presented category in the table, and an arbitrary p-value cut-off of 0.05 was used.
