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
purposeTransfemoral amputees face significant functional limitations with traditional socket prostheses. This study evaluates the efficacy and safety of the OPRA (Osseointegrated Prostheses for the Rehabilitation of Amputees) implant system in improving the quality of life for these patients.
methodsA retrospective study was conducted on 22 transfemoral amputees (20 male, 2 female; mean age 44.6 years) who underwent OPRA implant surgery between 2019 and 2021. Patients were assessed preoperatively and followed for two years post-surgery. Outcomes were measured using the Questionnaire for Persons with a Transfemoral Amputation (Q-TFA), pain scores, and complication rates.
resultsAt two-year follow-up, significant improvements were observed in Q-TFA scores for prosthetic use (30.41 ± 10.90 to 87.68 ± 11.42, p < 0.001), mobility (44.36 ± 15.57 to 71.45 ± 13.72, p < 0.001), problem score (52.40 ± 10.22 to 25.81 ± 9.66, p < 0.001), and global score (43.45 ± 10.87 to 74.95 ± 21.82, p < 0.001). Mean daily prosthesis usage increased from 3.77 ± 2.59 to 13.43 ± 3.76 h (p < 0.001). Complications included minor discharge (67.5%), significant discharge requiring surgical intervention (13.6%), prosthesis removal (9%), and periprosthetic fracture (4.5%).
conclusionThe OPRA implant system significantly improved functional outcomes and quality of life for transfemoral amputees over two years. While complication rates were notable, most were manageable with conservative treatment. These findings suggest that osseointegrated prostheses offer a promising alternative to socket prostheses for suitable candidates, though further research with larger cohorts is warranted to confirm long-term efficacy and safety.
