1 · What the graph read from it

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.

2 · The registry

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

Overactive bladder (OAB) remains challenging to treat due to drug intolerance and limited efficacy of behavioral therapies. The mechanistic basis by which exercise improves bladder function is poorly understood. Here, we established a clinically translatable resistance exercise model using graded treadmill loading (5-15% body weight [BW], 10-30 min/day) in a cyclophosphamide (CYP)-induced OAB rat model to identify the optimal therapeutic intensity and delineate redox-related mechanisms. Functional (urodynamics, urine spot test), MRI imaging, histological, immunofluorescence, and untargeted metabolomic analyses were integrated to assess detrusor remodeling and oxidative stress modulation across 11 experimental groups. ModeratSTREe resistance exercise (10% BW, 20 min/day) significantly increased bladder capacity (0.45 ± 0.17 mL-1.28 ± 0.44 mL) and prolonged voiding interval (2.13 ± 0.64 min-6.35 ± 0.93 min; p < 0.001). MRI and histology confirmed reversal of detrusor hypertrophy. Immunofluorescence demonstrated reduced 3-nitrotyrosine accumulation, indicating decreased peroxynitrite (ONOO⁻)-mediated nitrative stress. Metabolomic profiling revealed extensive reprogramming of glutathione metabolism, arginine biosynthesis, and glycine-serine pathways, restoring redox balance and antioxidant capacity. Integration of metabolic and histological data defined a mechanistic framework, "resistance exercise-peroxynitrite reduction-oxidative stress attenuation-detrusor remodeling." In conclusion, our findings identify peroxynitrite reduction and detrusor remodeling as key mechano-redox pathways through which resistance training improves bladder compliance and detrusor relaxation. These results highlight resistance exercise as a clinically feasible, non-pharmacological strategy with translational potential for improving outcomes in patients with OAB.
