Bijlsma et al. (2023) – Beoordeling door José

Databases from the Cochrane Library, MEDLINE, EMBASE, Airiti Library, PerioPath Index to Taiwan Periodical Literature, and Cumulative Index of Nursing and Allied Health (CINAHL) were searched from inception to April 2017. Randomized controlled trials (RCTs) focusing on lidocaine before nasogastric tube insertion were appraised. The primary outcome was the visual analog scale (VAS) score. The modified Jadad scale was used for quality assessment. Mean difference (MD) with 95% confidence intervals (95% CIs) and odds ratio (OR) for binary outcomes were assessed by a random effects model. Heterogeneity was determined by using the Cochran Q test and I^2 statistics. Publication bias was analyzed by using a funnel plot analysis.
