Nutritional status efficacy of early nutritional support in gastrointestinal care: A systematic review and meta-analysis.
Article in World journal of gastrointestinal surgery, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundGastrointestinal surgery is a complicated process used to treat many gastrointestinal diseases, and it is associated with a large trauma: Most patients often have different degrees of malnutrition and immune dysfunction before surgery and are prone to various infectious complications during postoperative recovery, thus affecting the efficacy of surgical treatment. Therefore, early postoperative nutritional support can provide essential nutritional supply, restore the intestinal barrier and reduce complication occurrence. However, different studies have shown different conclusions.
aimTo assess whether early postoperative nutritional support can improve the nutritional status of patients based on literature search and meta-analysis.
methodsArticles comparing the effect of early nutritional support and delayed nutritional support were retrieved from PubMed, EMBASE, Springer Link, Ovid, China National Knowledge Infrastructure, China Biology Medicine databases. Notably, only randomized controlled trial articles were retrieved from the databases (from establishment date to October 2022). The risk of bias of the included articles was determined using Cochrane Risk of Bias V2.0. The outcome indicators, such as albumin, prealbumin, and total protein, after statistical intervention were combined.
resultsFourteen literatures with 2145 adult patients undergoing gastrointestinal surgery (1138 patients (53.1%) receiving early postoperative nutritional support and 1007 patients (46.9%) receiving traditional nutritional support or delayed nutritional support) were included in this study. Seven of the 14 studies assessed early enteral nutrition while the other seven studies assessed early oral feeding. Furthermore, six literatures had "some risk of bias," and eight literatures had "low risk". The overall quality of the included studies was good. Meta-analysis showed that patients receiving early nutritional support had slightly higher serum albumin levels, than patients receiving delayed nutritional support [MD (mean difference) = 3.51, 95%CI: -0.05 to 7.07,
conclusionEarly enteral nutritional support can slightly shorten the defecation time and overall hospital stay, reduce complication incidence, and accelerate the rehabilitation process of patients undergoing gastrointestinal surgery.
