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

aimInformation regarding differences between general dentists (GDs) and endodontists in their daily practices is limited. The aim of this prospective cohort clinical study was to compare the details of clinical approaches of GDs and endodontists when performing non-surgical root canal treatments (NSRCT). METHODOLOGY: The study was conducted among 153 practitioners (104 GDs and 49 endodontists) in the National Dental Practice-Based Research Network in the United States who performed NSRCT on at least one of 1705 patients. Practitioners completed postoperative forms to document procedural data. Bivariate and multivariable analyses were performed to adjust for the potential effect of confounders. Two different multivariable models were tested to eliminate the impact of unstable variables.

resultsOverall, after adjusting for the tooth type, multivariable models showed that endodontists were significantly more likely than GDs to use magnifications >5×, rubber dam isolation, NaOCl irrigation, EDTA or H

conclusionsBased on actual clinical data, this study observed major differences between GDs and endodontists in their clinical approaches when performing NSRCTs. Further studies are needed to assess the effect of these differences on the outcome of NSRCTs.
