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

backgroundTemporomandibular joint disorders (TMD) are common musculoskeletal conditions affecting the masticatory system, leading to pain and functional limitations. Despite various conventional treatments, parts of the 2021 Korean Medicine Standard Clinical Practice Guidelines for TMD remain unaddressed due to insufficient supporting evidence for certain modalities like intraoral balancing appliances. This study aims to investigate a novel approach, temporomandibular joint balancing therapy (TBT), as a potential effective treatment.

methodsThis will be a single-center, randomized, assessor-blinded, parallel-group clinical trial. A total of 30 eligible participants aged 19 to 70 years with chronic TMD (VAS ≥ 40 mm for ≥ 3 months) will be randomized 1:1 to either the experimental group (TBT) or the control group (Transcutaneous Electrical Nerve Stimulation, TENS). Both interventions will be administered twice a week for 6 weeks (12 sessions). The primary outcome is the mean change in temporomandibular joint pain measured by the Visual Analog Scale (VAS, 100 mm) at 6 weeks compared to baseline. Secondary outcomes include worst TMD pain VAS, jaw range of motion (pain-free opening, maximum unassisted opening), Jaw Functional Limitation Scale (JFLS-8), DC/TMD Graded Chronic Pain Scale (GCPS 2.0), Treatment Expectancy Scale, Patient Global Impression of Change (PGIC), quality-adjusted life years (QALYs), EQ-5D, EQ-VAS, medical costs, lost productivity costs, and incremental cost-effectiveness ratio (ICER). Data will be collected at baseline, 6 weeks, and 10 weeks (for follow-up). Statistical analysis will compare outcomes between groups using appropriate methods, primarily intention-to-treat analysis. DISCUSSION: This study protocol details a randomized controlled trial designed to provide robust evidence on the efficacy, safety, and economic feasibility of TBT for TMD. The findings are expected to contribute to the evidence base for TMD management, potentially informing future clinical practice guidelines, particularly concerning the use of intraoral balancing appliances in Korean medicine.
