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
backgroundSense of Coherence (SOC) has been recognized as a significant psychosocial determinant of health. Evidence related to the relationship between SOC and oral health among adolescents and children are scarce. This study aimed to determine the associations between the SOC and oral health based on oral health status, oral health-related behaviours, and oral health-related quality of life in 15-year-old school children attending government schools in Kandy district, Sri Lanka.
methodsA cross-sectional study was conducted among 700, 15-year-olds attending government schools in Kandy district, Sri Lanka. Two-stage cluster sampling technique combined with the probability proportionate to size sampling method was used to select the participants. SOC was measured using a validated Sinhala version of the adolescents’ SOC questionnaire. Oral health behaviours and oral health-related quality of life were assessed using a self-reported questionnaire and a validated Sinhalese version of the 16-item Child Perception Questionnaire 11–14 (CPQ) respectively. Oral health status was determined based on the caries experience, bleeding on probing, and periodontal pocket depth. Independent associations between SOC and oral health indicators were determined using binary logistic regression models.
resultsParticipants with a low SOC were more likely to consume sugary foods daily (OR = 0.93, 95% CI: 0.88–0.97) compared to those with a high SOC when adjusted for confounding factors. SOC was associated with both the total CPQ score and domain-specific CPQ scores, with higher SOC scores indicating better oral health-related quality of life. SOC scores were not associated with oral health status.
conclusionSOC was associated with daily consumption of foods high in free sugars and good oral health-related quality of life. Therefore, interventions based on SOC could be used to enhance oral health behaviours and oral health-related quality of life of adolescents in Sri Lanka.
