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

The purpose of the present study was to explore the potential application of radiographic visibility of the root pulp in lower third molars in a northern Chinese population, in order to determine if this methodology can be used to prove whether a person has surpassed the thresholds of 18 and 21 years of age. A total of 1300 orthopantomograms comprising equal numbers of females and males evenly distributed between the ages of 15 and 40 years were analyzed. The radiographic visibility of the root pulp of the lower third molars was assessed using the stages described by Olze et al. (2010). Stage 1 first appeared at 19.25 years in males and at 20.73 years in females. The earliest appearance of stage 2 happened at 22.33 years in males and at 22.41 years in females. Stage 3 was achieved first at 26.45 years in males and at 27.66 years in females. It was concluded that stages 1, 2, and 3 can be used to show that a person is over 18 years of age. If stages 2 or 3 are determined, it is possible to prove that an individual has already attained the age of 21 years.
