From: Routine chest x-rays in intensive care units: a systematic review and meta-analysis
Effect of a restrictive versus routine chest x-ray strategy on intensive care unit length of stay in days among trials (primary analysis) and trials and observational studies (sensitivity analysis). The sample size of Hejblum et al. [13] has been adjusted for clustering (see Methods for details). Weight is the relative contribution of each study to the overall estimate of treatment effect using a random effects model.
