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.

Abstract

Introduction There has been speculation about early exfoliation of carious primary molar teeth treated with the Hall Technique (HT).Aim To investigate the hypothesis that there is a difference in exfoliation times between teeth treated with the HT and contralateral teeth not treated with the HT.Methods Split-mouth retrospective cohort study of children treated in Dundee Dental Hospital and School (DDH&S). Radiographs and clinical records were assessed to compare children's ages at exfoliation for HT-treated primary molars and their contralateral teeth not treated with the HT. Primary molars' root resorption was also evaluated to assess whether the HT influenced the rate of root resorption.Results Using DDH&S's clinical systems, children's records (n = 13,160) were screened for children's ages and sequential radiographs, with 192 children potentially eligible. After assessing radiographs and clinical records, 39 children met the inclusion criteria. Their mean age at time of HT treatment was 7.2 years (range = 4.0 to 11.0; SD = 1.5). There was no evidence of a difference (p = 0.41) between children's ages at exfoliation of HT teeth (10.7; SD = 1.2 years) and contralateral teeth (11.0; SD = 1.4 years).Conclusion There is no evidence that use of the Hall Technique is associated with early exfoliation of primary molars.
