1 · What the graph read from 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.

2 · The registry

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

purposeTo evaluate differential surgical interventions for obstructive sleep apnea (OSA) patients with single-level retropalatal based on the preoperative topographical diagnosis using nasoendoscopy with Müller's maneuver during supine position (MM-P). SUBJECTS AND

methodsThis case series included adult patients with OSA who showed a predominant single-level retropalatal collapse on MM-P. An anteroposterior pattern of collapse was managed by an anterior advancement procedure, while a transverse pattern of collapse was managed by lateral/anterolateral advancement procedures (double suspension sutures). A combined procedure was provided to the concentric type of collapse. All patients underwent evaluation of the polysomnography, Epworth Sleepiness Scale (ESS) values and snoring scores both preoperatively and 6-8 months after surgery.

resultsAmong 102 patients, the most commonly reported pattern of collapse at the retropalatal level was the concentric pattern (48.04%) followed by the transverse pattern (27.45%). The AP-pattern of collapse was reported in 24.51%. In the postoperative follow-up visits, no early or late complications were reported. All included groups showed significant improvement in polysomnographic data (mean AHI and lowest O

conclusionPreoperative differential diagnosis of OSA with MM-P allows for tailored surgical management. Tailored procedures could yield good surgical outcomes when patients are properly selected and the technique is chosen according to preoperative topographical diagnostic assessment. This study might provide an available less-costly and effective preoperative planning for OSA intervention. LEVEL OF EVIDENCE: 4.
