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

objectiveTo assess whether defects related to Molar Incisor Hypomineralisation (MIH) and Hypomineralised Second Primary Molar (HSPM), located on working cusps, exhibit greater extent and severity than those on balancing cusps. MATERIALS AND

methodsA total of 605 children aged 6 to 12 years were evaluated, of whom 110 presented with MIH/HSPM, comprising 268 molars (65 primary and 203 permanent). The molars were divided into two groups based on defect location: G1 (n = 170) with defects on working cusps, and G2 (n = 98) with defects on balancing cusps. Comparative assessments of defect location, extent, and severity were performed using Chi-square and Mann-Whitney tests, with a significance level of 5%.

resultsIn the overall sample, including both primary and permanent molars, no statistically significant differences were observed between G1 and G2 regarding extent (p = 0.15) or severity (p = 0.46). However, in primary molars only, significant differences were found for extent (p = 0.008), with greater lesion extension on working cusps, while severity showed no significant difference (p = 0.568).

conclusionHypomineralisation-related defects located on working cusps of primary molars exhibited greater extent than those on balancing cusps.
