Apnea-hypopnea index decreased significantly after nasal surgery for obstructive sleep apnea: A meta-analysis.
Synthesis in Medicine, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 23 papers, 1 of them a synthesis 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
backgroundNasal surgeries have been applied to obstructive sleep apnea (OSA) patients with nasal obstruction for decades. However, the efficiency of nasal surgery in improving OSA remains controversial.The aim of this study was to identify whether isolated nasal surgery can improve apnea-hypopnea index (AHI).
methodsComputerized searches were performed in MEDLINE, Web of Science, Cochrane Library, and Scopus from January 1, 2000 to April 30, 2016. A total of 18 articles and 587 participants were included. There were 1 randomized controlled trials, 2 nonrandomized trials, 11 prospective studies, and 4 retrospective studies. Data regarding study design (prospective/retrospective clinical trial, randomized, and controlled), population size, participant characteristics (age, gender, and body mass index), surgical intervention, and outcomes (AHI, Epworth sleep scale [ESS]) was collected.
resultsStatistically significant improvement in AHI (subgroup 1: weighted mean difference [WMD] [95%confidence interval (CI)], -4.17 [-7.62, -0.73]; subgroup 2: WMD [95%CI], -4.19 [-7.51, -0.88]; overall: WMD [95%CI], -4.15 [-6.48, -1.82]) and ESS (subgroup 1: WMD [95%CI], -2.14 [-3.08, -1.19]; subgroup 2: WMD [95%CI], -4.70 [-5.95, -3.44]; overall: WMD [95%CI], -4.08 [-5.27, -2.88]) was revealed.
conclusionBoth AHI and ESS improved significantly after isolated nasal surgery, but the improvement of AHI is slightly significant. Future randomized controlled trials are needed to confirm the long-term benefits of nasal surgery on OSA.
