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

objectivesTo systematically evaluate the postoperative disc-condyle relationship-including both structural position and functional mobility-following bilateral arthroscopic disc repositioning (Bi-ADRO) for temporomandibular joint disorders. MATERIAL AND

methodsThis retrospective study initially enrolled 90 consecutive patients who underwent MRI. After applying predefined inclusion and exclusion criteria, 31 patients without anterior disc displacement (non-ADD) were assigned to the symptomatic control group (group N), and 59 patients (101 joints) diagnosed with anterior disc displacement without reduction (ADDWoR) treated by Bi-ADRO constituted the surgical group (group A). Postoperative MRI was performed at 1, 3, and 6 months (A

resultsPreoperatively, group A

conclusionBi-ADRO restores sagittal disc position and improves joint mobility in patients with ADDWoR, although coronal disc displacement may persist. The degree of surgical overcorrection influences postoperative disc stability and coordinated disc-condylar movement. These findings support the use of quantitative MRI-based angular targets to optimize surgical outcomes, though longer-term studies are needed to confirm durability.
