The quality of the evidence was downgraded by two levels due to unclear risk of allocation concealment, performance and selection bias, and selective reporting
The quality of the evidence was downgraded by two levels as the 95% CI crossed 2 default MID thresholds (0.8 and 1.25)
The quality of the evidence was downgraded by one level as the 95% CI crossed 1 MID threshold (3.9 × +/− 0.5 = +/− 1.95)
The quality of the evidence was downgraded by one level as the 95% CI crossed 1 default MID threshold (1.25)
