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
purposeThe aim of the present study was to investigate the association between maternal depressive symptoms and Early Childhood Caries (ECC) in children residing in rural communities in southern Brazil.
methodsA population-based cross-sectional study was conducted with 236 children aged 1-5 years and their mothers. Mothers answered the Patient Health Questionnaire (PHQ-9) addressing depressive symptoms and a structured questionnaire investigating demographic, socioeconomic and behavioural characteristics. The mothers and children underwent oral health examinations using the WHO criteria (DMFT and dmft index, respectively). The outcome was the occurrence of ECC (dmft ≥ 1) and the main exposure was symptoms of maternal depression. Poisson regression with robust variance was used to estimate prevalence ratios and 95% confidence intervals adjusted for potential confounding variables.
resultsOverall, 37.7% of the children had ECC and 21.5% of the mothers had symptoms of depression. The prevalence of ECC was significantly higher among children of mothers with depressive symptoms (52.0%) compared to those of mothers without symptoms (34.6%). The multivariate analysis showed that the likelihood of ECC was nearly 50% higher in children whose mothers presented depressive symptoms (PR = 1.46; 95% CI 1.04-2.05) compared to those with mothers without depressive symptoms.
conclusionThe symptoms of maternal depression increased the likelihood of ECC in preschool children living in a rural area.
