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

objectivesThe aim of this study was to evaluate the diagnostic value of ultrasound in the obstructive pathology of the parotic gland not caused by sialolithiasis using sialendoscopy as reference standard.

methodsRetrospective analysis of all patients who presented with suspected diagnosis of obstructive ductal pathology of the parotid gland other than sialolithiasis between January 2011 and December 2017. 538 patients, for a total of 691 parotid glands were included in the study. Ultrasound was performed, followed by sialendoscopy in all cases. Duct diameter and parenchyma echogenicity were assessed. Direct sialendoscopic examination of the parotid duct was regarded as the reference standard.

resultsParotid glands with normal sialendoscopic findings (21.6%,

conclusionUltrasound parameters can be used to distinguish different types of obstructive ductal pathology of the parotid gland, supporting the use of this imaging modality as diagnostic tool of first choice.
