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: Urinary incontinence (UI) is involuntary urine leakage, mainly due to a feeling of high pressure in the abdominal part, the immediate and urgent need for micturition, or both. Neurotrophins (NTs) are a family of peptides that play a role in the regulation of nerve cells. Their effects on the lower urinary tract organs may provide a perspective to understand the development and diagnosis of UI. This study aims to investigate NT levels to understand how these molecules change in multiparous premenopausal women who suffer from stress-related UI. The study also evaluates diagnostic and distinguishing capabilities of NTs for these disorders. Methods: In this cross-sectional case-control study, multiparous premenopausal women underwent a urodynamic examination, a stress cough test, and were evaluated with an International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF). Participants were divided into three groups: 29 healthy women in the control group and two patient groups consisting of 26 women diagnosed with stress urinary incontinence (SUI) and 33 women diagnosed with mixed urinary incontinence (MUI). Nerve growth factor (NGF), brain-derived neurotrophic factor, neurotrophin-3 (NT-3), and neurotrophin-4 (NT-4) levels in serum were measured by enzyme-linked immunosorbent assay. The body mass index (BMI) and ICIQ-SF scores of the patients were also calculated. The data obtained were compared between the groups. Receiver-operating characteristic analysis was performed to determine the role of NTs in diagnosing UI. Results: The result showed that serum NGF and NT-3 levels were significantly low in both incontinence subtypes compared to the control group ( Conclusion: The differences in serum NGF and NT-3 levels were observed in multiparous premenopausal patients with UI. There was a decrease in serum NGF levels in MUI patients and serum NT-3 levels in SUI patients. Although the changes in serum NGF and NT-3 levels were significant, their discriminatory potential was weak or moderate.
