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

Nitinol compression staples are increasingly used in hand surgery due to their shape memory effect and simplified surgical technique. While they have demonstrated favorable outcomes, reports on complications and failure mechanisms remain limited. We report two cases of fixation failure: one in a vascularized proximal interphalangeal joint transfer and another in thumb carpometacarpal joint arthrodesis. Both cases required revision surgery with plate fixation. These cases suggest that failure resulted from asymmetrical force distribution. This was caused by one staple leg achieving only monocortical purchase while the other was bicortical, combined with a short working length. These cases highlight the critical importance of preoperative planning and precise staple placement, particularly when bone dimensions are unequal or the working length is limited.
