"Weekend Effect" in Patients With Upper Gastrointestinal Hemorrhage: A Systematic Review and Meta-analysis.
Synthesis in The American journal of gastroenterology, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 22 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectives"Weekend effect" refers to worse outcomes among patients presenting to the hospital on weekends or holidays. We performed a systematic review and meta-analysis of observational studies assessing the impact of the "weekend effect" in patients with upper gastrointestinal hemorrhage (UGIH).
methodsWe searched key bibliographic databases using keywords and MeSH terms related to gastrointestinal hemorrhage and "weekend effect". Our primary analysis evaluated mortality in patients with UGIH who were hospitalized on the weekend or after-hours compared with a weekday. Secondary outcomes included need for definitive therapy and length of hospital stay. Relevant data were extracted and meta-analyses were performed using random effects model. Subgroup sensitivity analyses were also performed to assess the effects of key variables.
resultsA total of 21 of 224 identified studies met inclusion criteria. Overall, there was no association between weekend admission and mortality among patients with UGIH (Odds Ratio (OR): 1.06; 95% confidence interval (CI): 0.99-1.14). However, meta-analysis using only the nine studies that did not report having a weekend rounder showed a significant increase in mortality (OR: 1.12; 95% CI: 1.07-1.17). There was no effect of weekend admission on any of our secondary outcomes.
conclusionsCurrent evidence suggests that weekend admission is associated with significant increase in mortality in patients with non-variceal UGIH but no difference in mortality was noted in patients with variceal UGIH. Our findings are relevant to policymakers, practitioners and providers who should ensure the creation of consistent quality and access to care throughout the week.
