WHICH FACTORS CAN DEFINE THE PROGNOSIS OF ARTICULAR FRACTURES OF THE CAPITELLUM AND TROCHLEA?
Article in Acta ortopedica brasileira, 2026. 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
Introduction: Articular fractures of the distal humerus involving the capitellum and trochlea (AO 13B3) are complex and challenging to manage without consensus in the literature on the most appropriate management. Objective: Evaluate radiographic features and treatment-related factors that may be positively or negatively correlated with the outcome of these fractures. Methods: Sixteen adult patients who underwent surgery between 2007 and 2024 with at least one year of follow-up were analyzed retrospectively. Radiographic characteristics, postoperative range of motion, and complications were evaluated. Statistical analysis used Odds Ratio (OR) and Fisher's Exact Test. Results: Elbow stiffness occurred in 56% of patients, 83% of which were in cases with posterior wall involvement (OR=7.5; p=0.08). Preoperative immobilization for more than seven days was associated with range of motion impairment (60%, OR=3; p=0.58) and ulnar nerve neuropathy (30%, OR=6; p=0.09). All cases of ulnar neuropathy occurred in women with prolonged immobilization (OR=8.08; p=0.09). Conclusion: Posterior wall integrity is a relevant prognostic factor for the final range of motion. The propensity for ulnar neuropathy in women and those with prolonged immobilization, although without statistical significance, suggests the need for larger samples.
