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

Atypical ulnar shaft fractures related to prolonged bisphosphonate therapy carry a considerable risk of nonunion due to compromised bone biology. A 70-year-old woman developed a persistent ulnar shaft nonunion with impaired biological healing after sustaining a low-energy injury following more than 10 years of bisphosphonate use. Conservative management was unsuccessful, and she was referred 8 months after injury with ongoing pain and radiographic evidence of an atypical ulnar fracture. Given the high risk of failure with conventional fixation and nonvascularized bone grafting, biological salvage was undertaken using a vascularized medial femoral condyle bone graft in combination with plate fixation. Radiographic bone union was achieved without complications, and satisfactory function was maintained at 1.5-year follow-up. This case demonstrates that vascularized bone grafting can serve as an effective salvage strategy for recalcitrant atypical ulnar shaft nonunion in patients with prolonged bisphosphonate exposure.
