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
Maxillomandibular advancement (MMA) represents an effective surgical treatment for individuals with obstructive sleep apnea (OSA) when conservative therapies fail. However, variability in surgical planning methods limits predictability and standardization of outcomes. This retrospective cohort study evaluated clinical and polysomnographic outcomes of MMA planned using the Barcelona Line (BL), and to explore the relationship between BL-guided skeletal positioning and treatment response in adult patients with moderate to severe OSA. Twenty-six consecutive patients (N = 26) underwent standardized virtual planning, surgery, and follow-up, with preoperative and postoperative polysomnography and three-dimensional CBCT analysis. Skeletal movements, upper airway changes, and sleep-related outcomes were assessed. Mean advancement at pogonion was 19.0 ± 4.7 mm. The apnea-hypopnea index decreased significantly from 45.8 ± 11.6 to 6.6 ± 6.6 events/h (mean relative reduction of 85.6 ± 10.9%). Treatment success was achieved in 25/26 patients (96.2%; 95% CI 81.1-99.3) and cure in 22/26 patients (84.6%; 95% CI 66.5-93.9). Daytime sleepiness improved, with ESS scores decreasing from 12.2 ± 1.2 to 1.5 ± 0.4. Total upper airway volume increased from 26.46 ± 2.88 mm
