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: GreenLight laser enucleation of the prostate (GreenLEP) offers superior hemostasis, raising the possibility of omitting postoperative continuous bladder irrigation. This study aimed to evaluate the feasibility and safety of an F16 small-diameter catheter non-irrigation protocol in BPH patients. Methods: A retrospective single-center study included 300 consecutive BPH patients undergoing GreenLEP at Yangjiang Hospital of Traditional Chinese Medicine between January 2024 and June 2025. The exposure was implementation of the F16 non-irrigation protocol. The primary outcome was successful completion without continuous bladder irrigation or secondary hemostatic intervention. Covariates included age, prostate volume (PV), operative time, ASA score, anticoagulant/antiplatelet use, urinary retention, preoperative catheterization, and concomitant bladder stones. Stratified analysis and ROC curve analysis were performed to explore predictors of failure. Results: Overall, 265 patients (88.3%) successfully completed the non-irrigation protocol. Median hemoglobin decrease was 2.0 g/L (IQR 1-3), with no blood transfusions. In the parsimonious multivariable logistic regression model adjusted for age, prostate volume, ASA classification, and anticoagulant/antiplatelet use, prostate volume was not independently associated with MajorFailure (adjusted OR 1.14 per 10-mL increase, 95% CI 0.76-1.71, Conclusion: The F16 non-irrigation protocol after GreenLEP is safe and feasible, with high success rates and minimal perioperative bleeding. Increased PV and anticoagulant therapy modestly reduce success but do not preclude application. These findings support broader implementation of non-irrigation strategies to enhance postoperative comfort and recovery.
