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
objectivesThe incidence and clinical characteristics of bi-rooted primary canines were investigated by performing oral panoramic radiographs.
methodsA total of 100 976 oral panoramic radiograph of subjects aged 3-9 years old were collected, and the incidence and distribution of bi-rooted primary canines were observed and recorded. The obtained data were analyzed using SPSS 25.0 statistical software, and the literature on bi-rooted primary canine was reviewed to record patient's data.
resultsThe incidence of bi-rooted primary canines was 0.37‰ (37/100 976), of which 0.59‰ (32/54 276) occurred in males and 0.12‰ (5/46 700) in females. Statistically significant difference was observed between males and females (
conclusionsBi-rooted primary canines are rare, mostly occur in 1-2 teeth, and are more common in males than females, in the upper jaw than in the lower jaw, and on both sides than on one side.
