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
Introduction: Radical prostatectomy (RP) is a standard curative treatment for localized Prostate cancer (PCa), but may negatively affect health-related quality of life (HRQoL) through urinary incontinence, erectile dysfunction, psychological distress, cognitive decline. Neurovascular bundle (NVB)-sparing techniques aim to preserve functional outcomes; however, their effects on neurocognitive performance remain unclear. Purpose: This study evaluated the impact of bilateral NVB-sparing RP on cognitive function, psychological status, HRQoL, and biochemical recurrence in patients with PCa. Methods: This retrospective study included 100 Caucasian patients who underwent laparoscopic RP between 2017 and 2022, either with bilateral intrafascial NVB preservation or without NVB sparing, according to European Association of Urology criteria. All surgeries were performed by high-volume surgeons with experience exceeding 250 RPs each. Cognitive function was assessed using a standardized computer-based test. Psychological and functional status was evaluated with the HADS Scale, ICIQ-UI SF and IIEF5 scale. HRQoL was measured with the EORTC QLQ-C30 and PR25 questionnaires. Serum prostate-specific antigen (PSA) and testosterone levels were analyzed. Results: Patients undergoing NVB-sparing RP demonstrated faster reaction times and better visual working memory compared with the non-NVB-sparing group. Postoperative erectile function, urinary continence, and testosterone levels were significantly superior following NVB preservation. HRQoL outcomes favored NVB-sparing RP, including higher global health status, physical, emotional, and cognitive functioning, and reduced fatigue. Anxiety and depression scores were lower but did not reach statistical significance. Lower postoperative PSA and absence of biochemical recurrence were associated with better verbal memory and executive functioning. No significant differences in BCR rates were observed between groups. Conclusion: Bilateral NVB-sparing RP preserves urinary and sexual function while supporting cognitive performance and psychosocial well-being, resulting in improved HRQoL without increasing the risk of BCR. These findings confirm the oncological safety of NVB-sparing RP and support the inclusion of neurocognitive and quality-of-life outcomes in surgical decision-making for patients with prostate cancer.
