  • Outcome variable was ln(16-RMI).

  • *Ventilator days and CRP were natural log transformed. Analyses conducted on the cohort of 123 patients who had blood sampling at 3 months. A complete case analysis approach was employed.

  • CRP, C-reactive protein; FCI, functional co-morbidity index; ICU, intensive care unit; RMI, Rivermead Mobility Index.
