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

backgroundDuring pulpectomy process on primary teeth, it is essential to opt for efficient and safe shaping to decrease the risk of iatrogenic errors and enhance irrigation and obturation quality. PURPOSE: The study aimed to evaluate and compare dentin thickness and centering ability of three file systems: paediatric rotary Rainbow Kids-e-Files MATERIALS AND

methodsA total of 81 mesial and distal canals from second primary mandibular molars were included in the study. CBCT images were taken before and after instrumentation for each group to measure the residual dentin thickness. Based on these measurements, the percentage of dentin removal and centering ability were evaluated for each group to compare the shaping efficiency of the file systems. The Shapiro-Wilk test was used to analyse the results using a one-way analysis of variance on rank (ANOVA), including pairwise multiple comparison procedures (Tukey test).

resultsNo significant difference was found in residual dentin thickness and centering ability between the three groups at any level (p value > 0.05). The Rainbow Kids-e-Files
