Socioeconomic, access-related, and periodontal factors associated with oral health-related quality of life among pregnant women in primary health care: a cross-sectional study.

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
backgroundPeriodontal disease affects not only clinical status but also oral-health–related quality of life (OHRQoL). Socioeconomic context, pregnancy-related systemic changes, hygiene habits, service access/use, and unmet periodontal needs may shape OHRQoL in pregnancy. This cross-sectional study aimed to identify factors associated with worse OHRQoL among pregnant women receiving care in the Brazilian Unified Health System (SUS).
methodsOHRQoL was assessed using the OHIP-14 questionnaire by standardized interview, and participants were categorized into: moderate/high impact (G1 = 56; OHIP-14 > 9) and no impact (G2 = 48; OHIP-14 = 0) on OHRQoL. Sociodemographic variables, systemic conditions, oral hygiene behaviors, access to prenatal dental care, and periodontal indicators were collected. Student’s t-test, Mann–Whitney, chi-square, and Poisson regression with robust variance were adopted (p < 0.05).
resultsG1 demonstrated lower educational attainment (p = 0.036) and frequency of daily toothbrushing (p = 0.024), with higher probing pocket depth (p = 0.003) and clinical attachment level (p < 0.001). Although 75% of the sample had a record of prenatal dental care, the absence of consultations was more prevalent in G1 (33.9%). The prevalence of periodontitis was also higher in this group (71.4% vs. 25.0%). In the multivariable analysis, three factors remained independently associated with worse OHRQoL: educational level, in which each additional year of schooling was associated with a lower prevalence of moderate/high OHRQoL impairment (PR = 0.96; 95% CI 0.92–0.99; p = 0.025), absence of prenatal dental care (PR = 1.49; 95% CI 1.11–1.99; p = 0.008), and greater severity of periodontitis in a dose–response gradient, with stage III showing the highest prevalence (PR = 2.93; 95% CI: 1.91–4.48; p < 0.001).
conclusionsSocial, access-related, and clinical vulnerabilities were associated with worse OHRQoL among pregnant women in primary health care. These findings reinforce the most recent Brazilian epidemiological data in dentistry (SB Brasil 2023) and support the need for integrated strategies in primary health care to expand effective prenatal dental care and prioritize periodontal disease prevention during pregnancy.
