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: Oral health during pregnancy is relevant to maternal well-being and has been associated with perinatal and child oral health outcomes. This study examined associations between a CAPSOM-derived composite knowledge, attitudes, and practices (KAP) score, oral hygiene behaviors, and clinical oral health indicators in pregnant women attending primary health care centers in Lanzarote, Spain. Methods: An observational cross-sectional study included 293 pregnant women. Sociodemographic, pregnancy-related, anthropometric, behavioral, and smoking-related variables were collected. Thirteen items based on the Maternal Oral Health Knowledge, Attitudes and Practices Questionnaire (CAPSOM) were combined into a composite KAP score. Clinical outcomes included Plaque Index, Gingival Index, and Tricolor Index. Hierarchical multiple linear regression models were fitted, with sensitivity analyses addressing potential overlap between behavioral variables and the composite KAP score. Additional adjusted models examined night-time toothbrushing. Results: Mean age was 29.81 ± 6.09 years and mean toothbrushing frequency was 2.29 ± 0.98 times/day. Overall, 96.6% brushed at least once daily and 78.5% reported night-time toothbrushing. Final models explained 60.7% of Plaque Index, 53.1% of Gingival Index, and 69.2% of Tricolor Index variance. Toothbrushing frequency was independently associated with lower values for all three outcomes. The composite KAP score showed modest independent associations with Plaque Index (B = -0.006, Conclusions: Oral hygiene behaviors, particularly toothbrushing frequency, showed stronger associations with clinical oral health indicators than the composite KAP score. The contribution of the composite score was modest and outcome dependent. These findings support combining oral health education with practical oral hygiene counseling in prenatal care.
