1 · What the graph read from it

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.

2 · The registry

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

Amandys is a radiocarpal pyrocarbon interposition implant indicated for degenerative wrists, showing promising medium-term results. The aim of this study was to evaluate the outcomes of the implant with a minimum follow-up of 10 years. This retrospective monocentric study included 84 implants in 76 patients who underwent the procedure. Preoperative and follow-up assessments included clinical evaluation, functional scores, and X-rays measurements. A total of 41 implants in 39 patients were evaluated at a mean follow-up of 12.64 years. At the final follow-up, average scores for pain (visual analogue scale) was 2.3, Patient-Rated Wrist Evaluation 26.3, QuickDASH 30.8. Grip strength was 71% of contralateral side. Flexion and extension were, respectively, 32 and 37 degrees. The satisfaction rate was 94.9%. There were 10 revision surgeries (13.6%); the survival rate was 86.4%. Radiological findings remained stable over time. The Amandys implant proves to be a durable alternative to wrist fusion and arthroplasty. The survival rate does not deteriorate at long term.
