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
Objective: To analyze risk factors of enteral nutrition (EN) diarrhea in intensive care unit (ICU) patients and to construct nomogram model. Methodology: A retrospective analysis was conducted on 402 patients who received EN treatment in the ICU of Shanghai Blue Cross Brain Hospital from January 2022 to January 2025. They were divided into diarrhea group and non-diarrhea group based on the occurrence of EN diarrhea. We used univariate and multivariate logistic regression analysis to identify risk factors for EN diarrhea. Construct a nomogram model for the occurrence of EN diarrhea in ICU patients based on independent risk factors and conduct goodness of fit tests. Results: The incidence of EN diarrhea in ICU patients was 29.85% (120/402). Hypoproteinemia, abdominal surgery in the last five days, fasting time > 5 days, antibiotic use > 2 weeks, no gradual increase in EN preparations, oral potassium preparations, EN liquid infusion rate ≥ 100ml/h, albumin level ≥ 35g/L were identified as risk factors for EN diarrhea (p<0.05). Based on the above influencing factors, a nomogram model was constructed and internally validated using the Bootstrap method. The nomogram model basically fitted with the ideal model. ROC area under curve (AUC) was 0.860 (95% CI: 0.820-0.901), indicating a certain predictive value for EN diarrhea. Conclusions: The nomogram model has high predictive power in predicting the risk of EN diarrhea in ICU patients. It is beneficial for screening high-risk patients and further adjusting nutritional therapy.
