In “Impact of a Postintensive Care Unit Multidisciplinary Follow-up on the Quality of Life (SUIVI-REA): Protocol for a Multicenter Randomized Controlled Trial” (JMIR Res Protoc 2022;11(5):e30496) the authors made three clarifications.
In the sample size section of the manuscript, the passage:
Therefore, we estimated that at least 50% had a very poor outcome, combining death and moderate to severe impairment of at least one EQ5D dimension
has been corrected to:
Therefore, we estimated that at least 50% had a very poor outcome, combining death and severe to extreme impairment of at least one EQ5D dimension.
In the sample size section of the manuscript, the passage:
The study was then powered to detect a decrease from 50% to 37% of patients with very unfavorable outcome with a power of 90% and a 2-sided 5% alpha risk, assuming this rate would be 50% in the control arm.

In the “statistical methods” section of the manuscript, the passage:
The 1-year survival rate without major deterioration in QoL (main endpoint, defined as reporting of an extreme problem” level in 1 of the 5 dimensions studied) will be compared between both arms using a piecewise exponential model considering any censorship and the repeated nature of observations, prohibiting the use of conventional methods of analysis of censored data

The correction will appear in the online version of the paper on the JMIR Publications website on April 14, 2023, together with the publication of this correction notice. Because this was made after submission to PubMed, PubMed Central, and other full-text repositories, the corrected article has also been resubmitted to those repositories.
