Risk Factors for Prolonged Postoperative Ileus in Colorectal Surgery: A Systematic Review and Meta-analysis.
Synthesis in World journal of surgery, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 35 papers, 4 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
backgroundProlonged postoperative ileus (PPOI) represents a frequent complication following colorectal surgery, affecting approximately 10-15% of these patients. The objective of this study was to evaluate the perioperative risk factors for PPOI development in colorectal surgery.
methodsThe present systematic review and meta-analysis was conducted in accordance with the PRISMA Statement. PubMed, EMBASE, SciELO, and LILACS databases were searched, without language or time restrictions, from inception until December 2018. The keywords used were: Ileus, colon, colorectal, sigmoid, rectal, postoperative, postoperatory, surgery, risk, factors. The Newcastle-Ottawa scale and the Jadad scale were used for bias assessment, while the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach was used for quality assessment of evidence on outcome levels.
resultsOf the 64 studies included, 42 were evaluated in the meta-analysis, comprising 29,736 patients (51.84% males; mean age 62 years), of whom 2844 (9.56%) developed PPOI. Significant risk factors for PPOI development were: male sex (OR 1.43; 95% CI 1.25-1.63), age (MD 3.17; 95% CI 1.63-4.71), cardiac comorbidities (OR 1.54; 95% CI 1.19-2.00), previous abdominal surgery (OR 1.44; 95% CI 1.19, 1.75), laparotomy (OR 2.47; 95% CI 1.77-3.44), and ostomy creation (OR 1.44; 95% CI 1.04-1.98). Included studies evidenced a moderate heterogeneity. The quality of evidence was regarded as very low-moderate according to the GRADE approach.
conclusionsMultiple factors, including demographic characteristics, past medical history, and surgical approach, may increase the risk of developing PPOI in colorectal surgery patients. The awareness of these will allow a more accurate assessment of PPOI risk in order to take measures to decrease its impact on this population.
