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
Purpose: Preoperative mental health challenges are associated with lower patient-reported outcomes following traumatic hand surgery. However, the association between mental health and recovery following regenerative peripheral nerve interface (RPNI), a surgical treatment option for upper-extremity (UE) neuromas, is not well characterized. This study investigated the outcomes of RPNI for UE neuromas in amputees and nonamputees, and evaluated for associations between preoperative mental health and patient-reported outcomes. We hypothesized that RPNI would improve pain and function, irrespective of baseline mental health or amputation status. Methods: A retrospective analysis of point-of-care data was conducted on patients undergoing RPNI for UE neuromas. Patient-reported outcome measures (PROMs) included the numerical 11-point visual analog scale (VAS) for pain, Patient-Reported Outcomes Measurement Information System (PROMIS) Upper Extremity (UE), Global Mental Health (GMH), and Global Physical Health (GPH). Patients were stratified into tertiles based on preoperative GMH scores, with the bottom third defined as "poor" preoperative mental health. Subgroup evaluations compared outcomes between amputees and nonamputees. Paired Results: Overall, VAS scores improved from 6.2 to 3.5, PROMIS UE improved from 29.5 to 31.0, and GPH improved from 40.3 to 41.8. Patients with lowest preoperative mental health scores showed greater VAS improvement (-3.3) than upper tertiles (-2.5). The lowest GMH tertile improved in PROMIS UE and GPH, as did the upper two tertiles. Amputees and nonamputees had comparable VAS improvements (-2.6 vs -2.8). Conclusions: Regenerative peripheral nerve interface resulted in clinically and statistically significant improvements in pain reduction ( Type of study/level of evidence: Therapeutic IV.
