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

background/purposeThe classic Stafne bone defect (SBD) is a rare small well-demarcated radiolucent lesion in the molar region of the mandible near the mandibular angle. This study reported a series of 5 SBD cases. MATERIALS AND

methodsThis study reviewed 4000 consecutive panoramic radiographs from February 2017 to May 2017 and found 5 classic SBD cases. The clinical and radiographic findings of these 5 SBD cases were reported.

resultsWe found 5 SBD cases presenting as small, well-defined, and radiolucent lesions at the typical first molar to third molar region of the mandible near the mandibular angle and below the mandibular canal. The mean age of the 5 patients at the time of diagnosis was 53.4 years (range, 45-69 years). All the 5 SBD cases occurred in male patients, 3 were on the right side and 2 were on the left side of the mandible. The mean greatest dimension of the 5 SBDs was 1.5 cm (range, 1.2-1.9 cm). All the 5 SBD cases were found incidentally on the panoramic radiographs and two of them were confirmed by cone-beam computed tomography. No surgical intervention was performed for these 5 SBD cases.

conclusionThe classic SBDs occur most frequently in male patients in the age group between 40 years and 60 years. For the SBDs at the typical site of the molar region of the mandible near the mandibular angle and below the mandibular canal, these lesions can be monitored by panoramic radiography once per one or two years.
