Effect of Perioperative Nutritional Supplementation on Postoperative Complications-Systematic Review and Meta-Analysis.
Synthesis in Journal of gastrointestinal surgery : official journal of the Society for Surgery of the Alimentary Tract, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 35 papers, 7 of them syntheses 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
backgroundPerioperative carbohydrate loading, increased protein intake, and immunonutrition may decrease postoperative complications. Studies on the topic have led to controversial results.
methodsWe searched Medline, EMBASE, and CENTRAL up to August 2018 for randomized trials comparing the effect of perioperative nutritional supplements (intervention) versus control on postoperative complications in patients undergoing gastrointestinal cancer surgery. Secondary outcomes included infectious complications and length of hospital stay (LOS). Random effects model was used to estimate the pooled risk ratio (RR) of treatment effects. Pooled mean difference (MD) was used to compare LOS. Heterogeneity was assessed using I
resultsOf 3951 articles, we identified 56 trials (n = 6370). Perioperative nutrition was associated with a lower risk of postoperative complications (RR 0.74, 95% confidence interval (CI) 0.69-0.80); postoperative infections (RR 0.71, 95% CI 0.64-0.79, n = 4582); and postoperative non-infectious complications (RR 0.79, 95% CI 0.71-0.87, n = 4883). There were no significant heterogeneity outcomes analyzed (I
conclusionPerioperative nutritional optimization decreases the risk of postoperative infectious and non-infectious complications. It also decreases LOS in patients undergoing gastrointestinal cancer surgery, but these findings should be taken with caution given the high heterogeneity.
