Rethinking Lafontaine Criteria: Second Metacarpal Cortical Percentage as a Reliable Predictor of Distal Radius Fracture Instability.

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
backgroundDistal radius fractures represent a significant cause of morbidity and loss of independence, particularly in older patients. There is no good consensus on which fractures managed nonoperatively will be unstable in a cast or splint other than Lafontaine criteria, the only relevant clinical study to date. Second metacarpal cortical percentage (2MCP) has been shown to be a reliable predictor of osteoporosis and poor bone quality. This study investigates the utility of 2MCP as an independent predictor of fracture displacement in nonoperative fracture management.
methodsA retrospective cohort of distal radius fractures treated conservatively over 7 years (2013-2020) was investigated. Injury, postreduction, and 4-week follow-up radiographs were reviewed for 2MCP, volar tilt, ulnar variance, and other demographic factors. Multivariate regression analysis was used to predict fracture displacement.
resultsOnly 2MCP and initial fracture displacement were associated with displacement at 4 weeks (
conclusionsSecond metacarpal cortical percentage is a useful clinical tool in predicting distal radius fracture instability. Clinicians can use 2MCP both in guiding decision-making when selecting patients who may benefit from operative management and as a screening tool for osteoporosis and initiation of antiresorptive therapy.
