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

aimThe aim of this study was to evaluate the association between obstructive sleep apnea (OSA) and periodontitis using an umbrella meta-analysis (MA).

methodsPubMed, MEDLINE, Web of Science, Scopus, Embase, and Google Scholar databases were systematically searched before December 2025. MAs reporting odds ratios (OR) for the association between OSA and periodontitis were included. Methodological quality was assessed using AMSTAR-2, and certainty of evidence was evaluated using GRADE. Random-effects MA was performed. Egger's test and trim-and-fill analysis were used to assess the publication bias.

resultsSeven MAs encompassing over 225,000 participants were included. A significant association was found between OSA and periodontitis (OR 1.96, 95% CI 1.68-2.29, p < 0.0001), with substantial heterogeneity (I

conclusionsThe results of this review suggest a significant association between OSA and periodontitis, with a greater association of severe OSA with periodontitis. Future studies should examine the impact of periodontal therapy on OSA severity and vice versa. PROSPERO REGISTRATION: CRD420251241137.
