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
introductionPerilunate dislocations (PLD) and perilunate fracture-dislocations (PLFD) are high-energy wrist injuries often linked to significant post-traumatic osteoarthritis. This study aims to determine whether PLD and PLFD yield different radiological outcomes following surgical treatment while identifying prognostic factors for worse outcomes. MATERIALS AND
methodsWe retrospectively analyzed 51 patients treated for perilunate injuries between 2000 and 2022. Radiographic evaluation included postoperative carpal alignment, scapholunate distance, ulnar translocation, and postoperative arthrosis according to the Kellgren-Lawrence scale. Logistic regression models were used in the study. The analyzed explanatory variables included: type of injury (PLFD/PLD), Mayfield classification, capsulodesis, repair of intercarpal- and extrinsic ligaments, and number of wrist transfixations. The significance level was set at p ≤ 0.05. The calculations were performed with R (version 4.3.2).
resultsAmong 51 patients, the mean follow-up was 4.33 years (1-22.13), and the mean age was 37.76 years. PLFD accounted for 55% of cases. Patients in the PLD group were older at the time of injury (p = 0.0031) compared to PLFD. Older patients presented also with higher stages of perilunate instability (p = 0.0061). Midcarpal arthrosis was the most common site of wrist degeneration (58.8%). Ordinal logistic regression indicated that PLFD was associated with a lower risk of midcarpal arthrosis (OR = 0.293, p = 0.04), while a higher number of wrist transfixations increased the risk of advanced arthrosis (OR = 2.427, p = 0.02), The logistic regression model detected a positive effect of the number of wrist transfixations on lunate fovea arthrosis (p = 0.048). The number of wrist transfixations did not correlate with the number of fractures (p = 0.06), Mayfield classification (p = 0.16), or intraoperative reduction outcome (p = 0.6).
conclusionPLD and a greater number of wrist transfixations were associated with a higher risk of wrist arthrosis. Limiting wrist pinning to essential procedures may help prevent additional iatrogenic chondral lesions.
