Interventions
Treatment
Prolonged Proning

Control
Prone position
16-hour prone positioning followed by up to 8-hour supine positioning

Risk of bias
Overall
The overall risk of bias reported in the table corresponds to the highest risk of bias for the outcomes assessed for the systematic review
Some concerns
General comment “In addition to the published article, the prospective study registry was used in data extraction and risk of bias assessment. Neither the protocol nor statistical analysis plan were available. There is no change from the trial registration in the intervention and control treatments. The primary outcome indicated in registry reflects the primary outcome reported in the paper. The study (n = 52) achieved its target sample size (n = 52)."
