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

objectivesThis study aims to evaluate the clinical efficacy and stability of customized total temporomandibular joint (TMJ) prosthesis by 3D printing from TMJ Yang's prosthesis system after five-years follow-up. MATERIALS AND

methodsThis prospective single-center case series study recruited patients required total TMJ prosthesis replacement from March 2016 to September 2022. Patient information was collected and followed up at 1 month, 3 months, 6 months, 1 year, 2 years and 5 years post-surgery. Using CT and panoramic scans to evaluate the prosthesis' position and bone integration. Pain, diet and mandibular function were evaluated by VAS score, and maximum interincisal opening, mouth opening deviation and mandibular maximum forward and lateral movement were recorded. Statistical analyses include descriptive statistics for demographic characteristics and paired t-tests and ANOVA for quantitative analysis.

results49 consecutive patients with an average age of 52.88 ± 13.78 years were included. The mean follow-up time was 5.00 ± 1.88 years. There were no postoperative infections, and the wound healed well. Patients' postoperative facial shape and occlusion remained unchanged except for one patient improved the facial shape by second-stage genioplasty. The position of the prosthesis was stable and the bone integration was satisfactory. After surgery, pain, mandibular function, and diet improved significantly (P < 0.05) and remained stable 1 year later. The maximum interincisal opening increased (P < 0.05), with mouth opening deviation and movement on the affected side similar to preoperative levels, but movement on the unaffected side and forward movement decreased slightly.

conclusionsThe customized total TMJ prosthesis by 3D printing from TMJ Yang's prosthesis system is safe, stable and effective during five years' clinical application. CLINICAL RELEVANCE: This study provides a new, safe and effective prosthesis option for temporomandibular joint reconstruction.
