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 oral health-related quality of life (OHRQoL) and factors associated with sleep bruxism (SB) in preschool children through a comparative cross-sectional study.
methodsOne hundred thirty-five preschool children (27 with SB and 108 without SB) were randomly selected from primary care units in the city of Diamantina, Minas Gerais, Brazil. The groups were matched for age, sex, and family income at a proportion of 1:4. Parents/guardians answered a questionnaire addressing sociodemographic and gestational characteristics as well as information on the child's health, and breastfeeding. The Brazilian version of the Early Childhood Oral Health Impact Scale (B-ECOHIS) was used to investigate the impact of oral problems on the OHRQoL of the preschool children, for which higher scores denote a greater negative impact. Oral clinical examinations were performed for the diagnosis of dental caries (dmft index), traumatic dental injuries, and malocclusion. Statistical analysis involved descriptive statistics as well as unadjusted and adjusted conditional logistic regression models (95%CI, p < 0.05).
resultsThe final adjusted logistic regression model revealed that children who resided in rural areas (OR = 3.75; 95%CI: 1.41-9.95; p = 0.008), those with cohabitating parents (OR = 3.99; 95%CI: 1.21-13.20; p = 0.023), and those with a Baume type II lower arch (OR = 3.35; 95%CI: 1.25-8.98; p = 0.016) were more likely to have SB.
conclusionThe occurrence of SB was greater in children who resided in rural areas, those with cohabitating parents, and those with a Baume type II lower arch. OHRQoL was not associated with the outcome.
