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

objectiveThe objective of this study was to evaluate the mesiobuccal (MB) root canal(s) anatomy of the maxillary first and second molar teeth in an Iranian population. MATERIALS AND

methodsCone beam computed tomography images of 280 teeth (145 maxillary first molars and 135 maxillary second molars) were analyzed to determine the number and types of the MB root canals. Chi-square test was used to examine the relationship between the number of MB canals and sex and Mann-Whitney analysis was used to define the relationship between the number of canals and the buccopalatal dimension of the MB roots. The level of interobservers' agreement was assessed with Kappa test.

resultsNearly 44.8% of the first molar and 18.5% of the second molar teeth had an additional MB canal (MB2). Types I and III of root canals had the highest frequencies. There was no significant relationship between the number of MB root canals of maxillary first and second molars and sex (

conclusionPresence of MB2 had a relatively high frequency, especially in the maxillary first molars. The mean buccopalatal dimension of the MB roots showed to be interrelated with the number of root canals.
