Nutrient Artery Canal of Femur Masquerading a Fracture Line: A Case Report.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Radiographic differentiation between true fracture lines and anatomical structures, such as nutrient artery canals, is crucial for optimal fracture management and postoperative mobilization. We present the case of a 54-year-old male with an AO 31A1.3 (AO/OTA 2018) pertrochanteric femur fracture treated with short trochanteric femoral nailing. Postoperative radiographs revealed an oblique radiolucent line adjacent to the distal part of the nail, raising suspicion of an undisplaced distal fracture extension. However, contralateral femoral imaging and CT scan confirmed the finding to be a nutrient artery canal. The patient was safely mobilized with full weight-bearing without the need for implant revision. Awareness of the radiographic features of nutrient artery canals is essential to avoid misinterpretation, unnecessary surgical modifications, and unwarranted delays in rehabilitation following fracture fixation.
