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

purposeTo assess the association between non-syndromic cleft lip and/or palate (NSCL/P) and developmental defects of enamel (DDE), including the DDE subtypes, such as molar-incisor hypomineralisation (MIH) and hypomineralised second primary molars (HSPM).

methodsThis cross-sectional study with a comparison group included individuals with and without NSCL/P ("NSCL/P group" and "control group," respectively). The NSCL/P group was recruited from a specialised craniofacial centre, and the control group was randomly selected from a population-based sample of schoolchildren, in a 1:2 ratio. DDEs were assessed by calibrated examiners through clinical examination. Associations between NSCL/P and DDE were analysed using univariate Poisson regression with robust variance (α = 5%), and comparisons between subtypes included Bonferroni-adjusted p values to account for multiple testing.

resultsThe sample included 164 children with NSCL/P and 328 controls (mean age = 8.09 ± 1.39 years). DDEs were more prevalent in the NSCL/P group (76.8%) than in controls (66.2%) (p < 0.01). Hypoplasia, demarcated opacities, and MIH/HSPM were significantly more frequent in the NSCL/P group (p < 0.01). Fluorosis was significantly more prevalent in the control group (p < 0.01). MIH was the most frequent DDE in the NSCL/P group (29.3%). DDEs in the anterior teeth were significantly associated with cleft laterality, being most frequent in bilateral clefts (p < 0.01).

conclusionChildren with NSCL/P have a higher prevalence of DDE than those without clefts. MIH was the most prevalent defect observed in this population, highlighting its clinical relevance.
