Comparison of decayed, missing, filled teeth index between thalassemia major patients and control group in Iran: a systematic review and meta-analysis.
Article in BDJ open, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
introductionScientific evidence of the association between Decayed, Missing, and Filled Teeth (DMFT) and thalassemia are conflicting and difficult to establish conclusions. Therefore, this study aimed to determine the relationship between dental caries (using the DMFT index) and thalassemia major using meta-analysis.
methodsDatabases were searched using such keywords as "Thalassemia," "Caries," "decay," "DMFT," "Iran," and OR operators, AND, and NOT. After the elimination of duplicate documentation, the articles which met the inclusion criteria were selected. Quality assessment was performed based on the Newcastle-Ottawa Quality Checklist. Thereafter, the standardized mean difference of the DMFT index was estimated.
resultsIn eight studies, the mean DMFT was compared between patients with thalassemia major and the control group. In six studies, the mean of this index was higher in patients with thalassemia major than in the control group and in all six of the studies, the differences were statistically significant. The mean standardized difference of DMFT, D, M, and F were reported as 1.36 (0.41, 2.30), 2.63 (0.42, 4.84), 1.65 (-0.14, 3.45), and 0.02 (-1.67, 1.72), respectively.
conclusionThe results of this meta-analysis indicated that DMFT index was more inappropriate in patients with thalassemia, as compared to the control group which represents the higher incidence of dental caries among patients with thalassemia compared to the control group.
