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

purposeThe therapy with mandibular advancement devices (MADs) represents a treatment option for patients with obstructive sleep apnea (OSA). The literature does not provide evidence regarding the most effective mandibular advancement; therefore, the aim of this systematic review with meta-regression was to investigate the effectiveness of different mandibular advancement amounts in reducing apnea-hypopnea index (AHI) in OSA patients.

methodsAn electronic search was performed in MEDLINE, Cochrane Database, Google Scholar Beta, ISI Web of Knowledge, Scopus, and LILACS to select randomized controlled trials (RCTs) investigating the efficacy of MADs in reducing AHI in adult OSA patients. Inclusion criteria were the diagnosis of OSA and success evaluation performed with a polysomnography, follow-up of maximum 12 months, and protrusion amount reported as a percentage of the maximum mandibular advancement. The quality of evidence was evaluated using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology. The success rate of each study was computed: [(mean AHI at baseline-mean AHI after treatment)/mean AHI at baseline].

resultsThirteen RCTs performing advancements from 50 to 89 % of maximum mandibular protrusion were included. The meta-regression analysis showed that advancement amounts higher than 50 % do not significantly influence the success rate (Q = 0.373, p = 0.541). According to the GRADE score system, the quality of evidence resulted to be moderate.

conclusionThe AHI improvement resulted to be not proportional to the mandibular advancement increase. It is plausible that the success of the therapy is influenced by a combination of variables that need closer study.
