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
purposeTo evaluate the knowledge, diagnostic ability, and clinical management of hypomineralised second primary molars (HSPM) among Brazilian dentists.
methodsA cross-sectional study was conducted among 283 Brazilian dentists (179 paediatric dentists and 104 non-paediatric dentists) using a structured online questionnaire. Data were collected on demographic characteristics, knowledge of HSPM, and clinical management across four scenarios of increasing severity (mild asymptomatic, mild with hypersensitivity, severe with post-eruptive breakdown, and HSPM associated with caries). Bivariate analyses and binary logistic regression were performed to compare groups and identify factors associated with diagnostic difficulty (p < 0.05).
resultsOverall familiarity with HSPM was high (91.9%); however, paediatric dentists were significantly more likely to differentiate it from other enamel defects than non-paediatric dentists (79.9% vs. 43.3%; p < 0.001). In the regression model, dental specialty was the only factor associated with diagnostic difficulty, with non-paediatric dentists showing higher odds of reporting uncertainty (OR = 4.69; 95% CI 2.56-8.56; p < 0.001). Clinical management followed a severity-based pattern, shifting from preventive approaches in mild cases to restorative interventions in more advanced conditions. Differences between groups were observed across several treatment options.
conclusionAlthough overall awareness of HSPM was high, differences in diagnostic confidence and clinical management were observed according to professional background.
