Validity of the Demirjian and Fishman Methods for Predicting Chronological Age Amongst Yemeni Children.

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.
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
objectivesThere has been an increasing need for reliable chronological age (CA) estimation in several aspects, including orthodontic treatment needs and legal, civil and forensic purposes. This study aimed to assess the validity of the Demirjian and Fishman methods in predicting the CA of Yemeni children.
methodsThis descriptive cross-sectional study was conducted at seven schools in Sana'a, Yemen, between December 2016 and December 2017. One orthopantomograph and one left hand-wrist X-ray were obtained for each child to calculate the dental age (DA) and skeletal age (SA) which were correlated and compared with the CA.
resultsA total of 358 Yemeni children aged 8-16 years were included in this study. The mean CA, DA and SA were 12.00 ± 2.25, 11.34 ± 2.42 and 12.39 ± 1.65 years, respectively. The Demirjian method significantly underestimated the CA by 0.58 ± 1.25 years in the total sample and 0.73 ± 1.30 and 0.40 ± 1.17 years in males and females, respectively (
conclusionsYemeni CA is highly correlated to DA and SA estimated by the Demirjian and Fishman methods, respectively. The Fishman method was more accurate amongst Yemeni females. Results showed that Yemeni children are delayed in dental development and skeletal maturity.
