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

STUDY

objectivesTo compare the efficiency of a TCM scoring system that includes 3 independent predictors obtained by physical examination, computed tomography, and polysomnography with the standard Friedman staging system that includes only physical examination variables for predicting surgical outcomes in patients with obstructive sleep apnea syndrome who undergo velopharyngeal surgery.

methodsThis prospective study was carried out in 265 patients with obstructive sleep apnea syndrome who underwent velopharyngeal surgery. All these patients were re-examined with polysomnography for evaluation of surgical outcomes at least 3 months after surgery. The efficacies in the surgical outcome prediction of 2 systems were calculated and compared.

resultsThe overall response rate and cure rate was 63.8% (169/265) and 22.3% (59/265), respectively. There were 32 patients with Friedman stage I, with a response rate and cure rate of 81.3% (26/32) and 28.1% (9/32), respectively, and 70 patients with TCM scores of < 14 with a response rate and cure rate of 91.4% (64/70) and 42.9% (30/70), respectively. Friedman stage and TCM grade were the only 2 factors independently predictive of surgical response (

conclusionsCompared with the Friedman staging system, the TCM scoring system was more efficient in selecting proper candidates for velopharyngeal surgery. The main reason may be its better utilization of patients' preoperative information, especially the inclusion of physiological factors. CLINICAL
