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
objectiveTo evaluate non-invasive biomarkers of detrusor underactivity (DU) in men with benign prostatic enlargement (BPE) and their ability to predict clinical and urodynamic improvement following prostate surgery. Particular attention was given to urinary adenosine triphosphate (ATP) levels, bladder contractility index (BCI), and bladder voiding efficiency (BVE).
methodsThis exploratory study included 24 men with BPE undergoing prostate surgery. Based on pre-operative pressure-flow studies (P/F studies), patients were divided into DU (BCI < 100) and non-DU (BCI ≥ 100) groups. Urinary ATP levels were compared among DU patients, non-DU patients, and age-matched healthy male volunteers. Clinical and urodynamic parameters, including BCI and BVE, were assessed before and 1 year after surgery.
resultsThirteen patients were classified as DU, and 11 as non-DU. Median urinary ATP levels did not differ between groups. One year after surgery, DU patients presented a significant improvement in International Prostate Symptom Score, quality of life, Qmax, and post-void residual volume. However, median BCI did not increase after surgery. Apart from BCI, all other parameters were similar between groups after surgery. In this cohort, all DU patients with a pre-operative BVE > 40% achieved surgical success, compared to <50% of those with BVE < 40%.
conclusionUrinary ATP does not appear to be a useful DU biomarker in men with BPE. Although prostate surgery did not significantly improve detrusor function 1 year after surgery, most DU patients experienced clinical improvement. Pre-operative BVE seems a simple non-invasive tool to identify DU patients more likely to benefit from surgery.
