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

objectiveTo describe the proportions of different osseous diagnoses in older patients with temporomandibular disorders (TMD) and to analyze the symptoms, disc position, occluding pairs, and facial skeletal characteristics of patients with bilateral osteoarthrosis (BOA) and bilateral normal joints (BNJ).

methodsThis retrospective cross-sectional study constituted 88 older patients (age ≥60 years). The osseous diagnosis, symptoms, disc position, occluding pairs, and facial skeletal characteristics were evaluated. Variables in BOA patients and BNJ patients were compared using the

resultsForty-eight patients had BOA, 7 had unilateral osteoarthrosis, 11 had intermediate osteoarthrosis, and 22 had BNJ. The prevalence of disc displacement without reduction (DDw/oR) in BOA patients was significantly higher than in BNJ patients. BOA patients exhibited greater ANB angle, PP-MP, U1-NPo, L1-NPo, and facial convexity angle; shorter posterior cranial base; and decreased ramus height.

conclusionBOA patients with associated DDw/oR had more complaints of orofacial pain and exhibited a shorter posterior cranial base, and greater mandibular retrusion, anterior tooth protrusion, and protruded profile than BNJ patients.
