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 establish a prediction model for the risk of inadequate bowel preparation for colonoscopy in the elderly, and to validate the model to test its prediction effect. Methods: A total 927 patients who underwent colonoscopy in the First Affiliated Hospital to Chongqing Medical and Pharmaceutical College from January to December 2023 were selected as the modeling group, and were divided into the success group (839 patients) and failure group (88 patients) according to whether or not inadequate bowel preparation occurred, and then a logistic regression prediction model was established and transformed into a risk scoring system. The area under the ROC curve and the Hosmer-Lemeshow test were used for model differentiation and calibration, respectively, and the 10-fold cross-validation method was used for internal validation of the model. A total of 548 patients who underwent colonoscopy in our hospital from January to June 2024 were selected for external validation of the model. Results: Logistic regression analysis showed that age ≥65 years, diabetes mellitus, exercise habits, Bristol stool characterization scale, frailty, and ambulatory functional status were independent factors influencing the inadequate bowel preparation for colonoscopy in the elderly. The area under the ROC curve for the modeling group was 0.806, and the Hosmer-Lemeshow test showed p=0.870. The area under the ROC curve of the validation group was (0.785±0.090). The area under the ROC curve of the validation group was 0.824, and the Hosmer-Lemeshow test showed Conclusion: The predictive model of the risk of inadequate bowel preparation for colonoscopy in elderly people can predict the risk of inadequate bowel preparation in elderly people, and can be used as a tool for clinical caregivers to screen the high-risk group of inadequate bowel preparation in the elderly.
