The effect of tongue strength and endurance in patients with obstructive sleep apnea.

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
purposeThis study aimed to evaluate tongue strength and endurance in patients with OSA and identify variables that modify their effects on OSA severity.
methodsA cross-sectional study included 189 adults with OSA, classified according to the apnea-hypopnea index (AHI) as mild (n = 63), moderate (n = 52), or severe (n = 74). The anterior and posterior tongue strengths, and tongue endurance were measured using the IOPI
resultsThe anterior tongue strength did not differ significantly across mild, moderate, and severe OSA (56.11 ± 11.31 vs. 51.32 ± 10.67 vs. 55.55 ± 13.22 kPa, p = 0.07), nor did posterior tongue strength (50.16 ± 16.14 vs. 46.25 ± 12.55 vs. 47.84 ± 13.39 kPa, p = 0.328), or tongue endurance (16.00 (12,22) vs. 14.75 (12,17.5) vs. 17.30 (13,23) seconds, p = 0.744). BMI was a significant effect modifier for anterior and posterior tongue strength. In the non-obese subgroup (BMI < 30 kg/m
conclusionIn an adult cohort, tongue strength did not differ among patients with mild, moderate, and severe OSA. However, in non-obese patients (BMI < 30 kg/m²), tongue strength was lower in those with severe OSA compared to those with mild OSA. Future studies on the impact of tongue strength may be best directed at non-obese patients with OSA.
