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

purposeThe influence of body mass index (BMI) on fracture healing after femoral shaft intramedullary nailing remains unclear, particularly regarding postoperative weight-bearing decisions. This study evaluated whether elevated BMI was associated with delayed union after intramedullary nailing of adult femoral shaft fractures and whether weight-bearing protocol modified this association.

methodsThis retrospective cohort study included adults with AO/OTA 32 femoral shaft fractures treated with intramedullary nailing at a Level I trauma center between November 2021 and April 2025. Patients with more than 6 months of clinical and radiographic follow-up were included. The primary exposure was BMI ≥ 25 kg/m

resultsThe final cohort included 174 patients: 53 with BMI < 25 kg/m

conclusionBMI ≥ 25 kg/m
