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
introductionThe treatment of acetabular fractures with pelvic reconstruction is technically challenging and labor-intensive and carries high complication rates. This retrospective review compares the treatment of acetabular fractures with a trabecular metal cage with a cemented bimobile acetabular component versus a cemented polyethylene liner and dual mobility articulation, in addition to open reduction internal fixation (ORIF) of the acetabulum. Methods: This retrospective single surgeon review included all patients aged 18 or older who presented with an acetabular fracture between 2015 and 2025 at an academic, tertiary trauma and elective arthroplasty referral center (UF Health Gainesville). The surgical technique included treatment with a trabecular metal cage with a cemented polyethylene liner or a metal bimobile acetabular component.
resultsForty-six patients were included in the final sample, 26 in the metal bimobile component group and 20 in the polyethylene component group. Patients receiving a polyethylene component (63.3±14.9) were significantly younger than those receiving a metal bimobile component (73.1± 10.7, p=0.03). Patients receiving a polyethylene component had a shorter hospital length of stay than patients receiving a metal bimobile component (p=0.02). The rate of heterotopic ossification was similar between groups at a minimum of six months post-surgery, as assessed via Brooker classification. Conclusions: We found comparable outcomes in the treatment of acetabular fractures with a trabecular metal cage using either a cemented bimobile component or a polyethylene liner with subsequent ORIF. Either component may serve in fixation for elderly acetabular fractures, particularly in patients with pre-existing osteoarthritis, osteoporosis, concomitant femoral head fractures, and marginal impaction.
