Genetic predictive links between oropharyngeal microecology and obstructive sleep apnea syndrome: expanding the perspective of etiology.
Review in Journal of oral microbiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
Background: Obstructive sleep apnea syndrome (OSAS), a global public health concern, is linked to oropharyngeal microbiota, but observational studies cannot confirm their causal association. Objective: To explore the potential causal relationship between oropharyngeal microecology and OSAS. Methods: The data related to the oropharyngeal microbiome and this disease were obtained from China Nucleotide Sequence Archive and genome-wide association studies. Moreover, we screened qualified single nucleotide polymorphisms as instrumental variables. Two-sample Mendelian randomization bidirectional analysis was conducted using methods such as Wald ratio and inverse-variance weighted. The horizontal pleiotropy was judged by the MR-Egger intercept, and the sensitivity analysis was conducted by the "Leave-one-out" method and Cochran's Q assessment. Results: Interferences in the abundance of specific strains of oropharynx (overall, the Firmicutes/Bacteroidetes phylum ratio ↑) raised the risk of OSAS, such as increased Streptococcus mgs 2253 (OR = 4.280) and decreased Prevotella mgs 3161 (OR = 0.218). Conversely, OSAS also affected the abundance of some oropharyngeal microorganisms, such as a decrease in Neisseria lactamica mgs 343 and an increase in Pauljensenia mgs 2308. Conclusion: This study emphasizes the causal relationship between oropharyngeal microecology and OSAS, expands the new etiological mechanism, and provides potential novel strategies for the prevention and treatment of OSAS.
