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

objectiveThe aim of the present study was to evaluate the symptoms of temporomandibular dysfunction (TMD) in patients with obstructive sleep apnea treated with long-term use of an oral appliance (OA) using a questionnaire based on the Helkimo Anamnestic Dysfunction Index. A further aim of the study was to evaluate the presence of daytime sleepiness using the Epworth Sleep Scale (ESS) and otologic symptoms. MATERIALS AND

methodsPolysomnograms of 34 patients were performed at baseline and after 6 months of OA use. As follow-up, the patients were contacted by telephone interview to answer the same questionnaires after 36.0 +/- 17.0 months. RESULTS AND DISCUSSION: The intensity of TMD symptoms decreased significantly throughout treatment (p < 0.01). ESS values improved from 12.2 +/- 5.0 to 6.9 +/- 2.6 (p < or = 0.05). Tinnitus was present in nine patients at baseline and decreased in intensity in seven patients by the final assessment while remaining at the same level in two patients.

conclusionsWe conclude that long-term usage of an OA does not cause impairment to the temporomandibular joint. The Helkimo and otologic indexes are simple and useful in long-term patient follow-up. There was a long-term improvement in the ESS values over the years analyzed. A follow-up program could increase compliance by motivating patients to use the device regularly.
