The effect of supplementary parenteral nutrition with different energy intakes on clinical outcomes of patients after gastric cancer surgery.
Article in BMC surgery, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundTo investigate the effect of postoperative supplementary parenteral nutrition (SPN) containing varying energy intake levels during the early postoperative period on the clinical outcomes of patients diagnosed with gastric cancer.
methodsData from 237 patients, who were diagnosed with gastric cancer between January 2016 and June 2022, were retrospectively analyzed. Patients were divided into 2 groups based on mean daily SPN energy intake: low (L-SPN; < 20 kcal/kg/day); and high (H-SPN; ≥ 20 kcal/kg/day). Data regarding gender, age, body mass index, preoperative Nutrition Risk Screening 2002 (NRS 2002) score, American Society of Anesthesiologists Physical Status classification system, age-adjusted Charlson Comorbidity Index, diabetes, hypertension, chronic lung disease, and the Tumor-Node-Metastasis (TNM [Eighth edition]) classification were collected for propensity score matching (PSM). Postoperative indicators were monitored. A power analysis was performed during the design phase of this study to ensure that statistical power exceeded 80% to reliably detect differences between the 2 groups.
resultsAfter PSM, data from 128 patients were analyzed (H-SPN, n = 64; L-SPN, n = 64). The H-SPN group experienced shorter postoperative hospital stay (8.11 ± 6.00 days vs. 10.38 ± 7.73 days; P = 0.045) and a lower number of infectious complications (36 [56.3%] vs. 60 [93.8%]; P < 0.001), particularly pulmonary infections, compared with the L-SPN group. Additionally, no increase in hospitalization costs or non-infectious complications occurred in the H-SPN group. Subgroup analysis revealed that H-SPN significantly reduced the incidence of infectious complications among those < 65 years of age (hazard ratio [HR] [95% confidence interval (CI) 0.240 0.069-0.829]; P = 0.024), NRS 2002 score ≥ 3 (HR 0.417 [95% CI 0.156-0.823]; P = 0.028), age-adjusted Charlson Complexity Index < 2 (HR 0.106 [95% CI 0.013-0.835]; P = 0.033), and TNM stage III (HR 0.504 [95% CI 0.224-0.921]; P = 0.046).
conclusionsH-SPN effectively reduced postoperative infectious complications and the length of hospital stay, suggesting that early postoperative H-SPN may be an advantageous nutritional support strategy for patients diagnosed with gastric cancer.
