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
Background: The factors affecting depression in schizophrenia are complex and diverse and have been well reported in the literature. However, few studies have investigated the relationship and potential mediating pathways between oral health-related quality of life (OHRQoL), internal protective factors of oral health such as oral health literacy (OHL) and oral health-related self-efficacy (OH-SE) and depression in patients with schizophrenia. This study adopts structural equation model (SEM) to explore the hypothesized model of the interrelationship among OHRQoL, internal protective factors of oral health and depression in patients with schizophrenia. Methods: Patients with schizophrenia (n = 300) were conveniently recruited from a psychiatric hospital in China between September and November 2024, based on their availability and willingness to participate. Four validated self-report scales (Oral Health Impact Profile Scale (OHIP-14), Short-Form Health Literacy Dental Scale (HeLD-14), Self-Efficacy Scale for Self-Care (SESS), Self-Rating Depression Scale (SDS)) were used to collect data. We adopted SEM, mediation analyses and path analyses to explore the relationships among OHRQoL, OHL, OH-SE, and Depression. Results: The hypothesized model demonstrated acceptable model fit parameters: χ Conclusion: This study provides novel evidence for the pathway OHRQoL → OH-SE → OHL → Depression. Clinicians may use this model as theoretical evidence to formulate targeted pathway-based interventions that enhance internal protective factors of oral health, which may improve OHRQoL while alleviating depressive symptoms, although causal inferences cannot be drawn from this cross-sectional study.
