Primary outcome
	In the register Yes
	In the report Ventilator-free days during the first 28 days, defined as the number of days alive and free from mechanical ventilation for at least 48 consecutive hours.
Documents avalaible	Protocol Yes. In English Statistical plan Yes Data-sharing stated Yes
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 all available versions of the published article, the study registry, statistical analysis plan and protocol were used in data extraction and risk of bias assessment. The study was terminated early. As a result, the target sample size (350) was not achieved. Quote:
