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

Objectives: To report the clinical and functional outcomes of patients undergoing total temporomandibular joint (TMJ) replacement with customized prostheses. Materials and Methods: Six female patients treated between 2018 and 2024 for advanced TMJ pathology-severe osteoarthritis (n=5) or condylar osteochondroma (n=1)-were included. All underwent unilateral total joint replacement using customized prostheses planned with cone-beam computed tomography and magnetic resonance imaging. Interincisal mouth opening (IMO), pain (visual analog scale), jaw function (JF), and dietary intake (DI), assessed through a Likert-type psychometric scale, were recorded preoperatively and during a minimum follow-up of 24 months. Results: All patients showed postoperative improvement. Median JF decreased from 6.5 to 3.5, DI from 8 to 1.5, and pain from 7 to 2. Postoperative IMO averaged 32 to 33 mm. One patient required revision for screw displacement without long-term functional compromise. Conclusion: Customized TMJ prostheses proved safe and effective, demonstrating consistent improvements in pain, mandibular function, and dietary capacity in patients with severe joint disease. This approach represents a reliable therapeutic option when combined with individualized surgical planning.
