Racial variations in maxillomandibular advancement for obstructive sleep apnea: a systematic review and meta-analysis.
Synthesis in Sleep & breathing = Schlaf & Atmung, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 2 of them syntheses that pooled 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.
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
purposeWe aimed to explore alterations in polysomnographic, cephalometric, and subjective outcomes amongst different ethnic/racial groups after MMA for OSA.
methodsA meta-analysis was performed according to PRISMA reporting guidelines. The COCHRANE Library, CINAHL, PubMed, and Scopus were searched from inception to August 8, 2023. Each measure was weighted according to the number of patients affected. Heterogeneity among studies was assessed using χ2 and I2 statistics with fixed effects (I
resultsTwenty studies with a total of 469 patients (n = 257 Caucasians, n = 204 Asians, n = 8 Latinos) with a mean patient age of 40.0 years (range: 18-67; 95% CI: 38.0, 42.1). The mean difference for Caucasians were AHI: -39.6 (95% CI: -55.0, -24.1; p <.001), LSAT: 7.5 (95% CI: 5.7, 9.3; p <.0001), and ESS: -4.5 (95% CI: -5.6, -3.4; p <.0001). The mean difference for Asians were AHI: -42.7 (95% CI -49.3, -36.0; p <.0001), LSAT: 13.8 (95% CI: 10.0, 17.4; p <.0001), and ESS: -6.7 (95% CI: -9.9, -3.5; p <.0001). The mean difference for Latinos were AHI: -21.2 (95 CI%: -37.7, -4.6; p =.01), and ESS: -2.0 (-7.9, 3.9; p =.50). Greater reduction of AHI was seen in Asians vs. Caucasians and Asians vs. Latinos. Lastly, the reduction of ESS was significantly better for Asians vs. Caucasians.
conclusionThe study highlights significant variations in MMA outcomes among different ethnic/racial groups. Asians tend to have more severe OSA preoperatively and experience greater postoperative improvements in AHI, LSAT, and ESS compared to Caucasians.
