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

purposeTo compare the proximity of rafting screws to the articular surface in lateral split-depression (LSD) tibial plateau fractures using mini-fragment (MF) and pre-contoured anterolateral (AL) proximal tibia plates. Secondary aims included comparing patient-reported outcome scores and rates of hardware failure and reoperation.

methodsDesign Retrospective review.

settingMulti-center Level I Tertiary Academic Center. Patient Selection Criteria: Adult patients with AO/OTA 41B3.1 LSD tibial plateau fractures treated over 30 months by a single surgeon were identified. Patients were included when their fractures were treated with either a MF T-plate (2.7 mm in thickness) or a pre-contoured anatomic AL plate.

main outcome measuresThe primary outcome was the distance from the lateral joint line to the most proximal screw (screw-to-joint distance [SJD]) as measured on intraoperative fluoroscopy.

resultsTwenty-four patients were included with patients having received either a 2.7-mm MF T-plate (n = 14) or a standard AL proximal tibia plate (n = 10) and were followed for a median time of 29 weeks. Average SJD was 3.79 mm in the MF group and 8.67 mm in the AL group (p < 0.001). There was no difference in PROMIS scores between the groups. No patients experienced loss of reduction, implant loosening/failure, reoperation, or removal of tibial plateau hardware.

conclusionsMini-fragment plates allow for a significantly shorter SJD compared to AL plates, allowing surgeons to provide more proximal rafting of LSD fractures while maintaining low rates of postoperative complications. No increase in fracture subsidence was observed when using mini-fragment fixation alone compared to AL plates.
