Nicodemo's method on dental development: a cross-sectional study with 3,271 children and adolescents.
Article in Brazilian oral research, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled 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.
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
Civil and criminal forensics utilize dental development to estimate age. The method of Nicodemo, Moraes, and Médici Filho (NMM) is a popular dental age estimation tool in South America; however, it lacks a scientific basis for applications in contemporary forensic practice. This research included the largest sample ever collected in Brazil for a similar purpose. The sample consisted of 3,271 panoramic radiographs of female (n = 1,634) and male (n = 1,637) individuals between six and 22.9 years old (mean 14.6 ± 4.9 years). The applied NMM method considered all maxillary and mandibular left permanent teeth (n = 16). The fit between the chronological age and estimated age intervals was assessed, and a correlation test with Lin's correlation coefficient was performed. The overall percentage of fit was 22.5%, without statistically significant differences based on sex (p > 0.05). The percentage of fit was greater in younger individuals, such as those aged 6-6.99 years (90%), and progressively decreased in older individuals, such as those aged 11-11.9 years (18.2%). After 12 years of age, the method could not provide correct classifications up to 25 years of age. Lin's correlation coefficient was predominantly low (ρ = 0.175; 0.367). NMM is considerably limited, and current forensic practice should not apply it to estimate dental age.
