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
objectiveTo evaluate the effect of obstructive sleep apnoea (OSA) surgery on insomnia in patients with co-morbid insomnia and sleep apnoea (COMISA).
methodsA retrospective interventional study was conducted on fifty consecutive adult patients with OSA who underwent surgery for OSA. Outcome measures included the Insomnia Severity Index (ISI) and the following polysomnography (PSG) indices: apnoea-hypopnea index (AHI), oxygen saturation index (ODI), lowest oxygen saturation (LOS) and Epworth Sleepiness Score (ESS) before treatment and at 4 months post-operatively.
resultsIn our study, 36% of the patients had clinical insomnia (ISI score > 15) prior to surgery. Following OSA surgery, there was an average improvement in the total ISI scores from 19.82 to 5.65 (p < 0.05). One patient continued to have moderate to severe clinical insomnia. Overall OSA parameters following surgery showed AHI decreased from 33.38 ± 23.76 to 18.37 ± 22.94 (p < 0.05); ODI reduced from 30.85 ± 22.37 to 16.77 ± 21.73 (p < 0.05); LOS significantly increased from 74.42 ± 11.93 to 87.70 ± 7.59 (p < 0.05); ESS showed significant reduction from 10 ± 5.9 to 6.55 ± 5.18 (p < 0.05).
conclusionOur results showed a reduction in the insomnia scores of our COMISA subgroup and a significant post-operative improvement in ambulatory polysomograph variables. OSA and insomnia are strongly correlated and surgical treatment of OSA appears to be effective in reducing the insomnia burden in COMISA patients.
