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
Introduction: Vaccination coverage among pregnant women in Brazil remains poorly documented, particularly in low-resource settings. This study aimed to (1) assess the completeness of vaccine records on prenatal cards and (2) evaluate pregnant women's knowledge of vaccines recommended by the Brazilian National Immunization Program (NIP). Methods: : A cross-sectional study was conducted at the Hospital Estadual de Presidente Prudente (HEPP), a public secondary hospital in São Paulo, Brazil, between August 2022 and April 2023. The study population comprised 1,130 women admitted for delivery, of whom 541 (47.9%) had prenatal cards available for review. Postpartum, data from the prenatal cards were extracted, and participants completed a structured questionnaire to assess their vaccine knowledge. Sociodemographic data were obtained from electronic medical records. Univariate analyses were performed using Pearson's Chi-Squared or Fisher's Exact Test. Only 11.2% of the reviewed prenatal cards documented complete vaccination with all four NIP-recommended vaccines, while 31% contained no vaccine records at all. The tetanus, diphtheria, and acellular pertussis (Tdap) vaccine had the highest documented coverage (61%). The mean age of participants was 27.1 ± 0.3 years. Although most participants (91.1%) believed they had been vaccinated during pregnancy, only 61.5% could specify which vaccines they had received. No significant association was found between sociodemographic factors and the completeness of vaccine documentation. The low level of vaccination documentation and the critical knowledge gaps identified in this study highlight deficiencies in the quality of prenatal care within Brazil's Unified Health System (SUS) in the Western region of São Paulo state. Addressing these issues requires concerted efforts to improve healthcare provider training, strengthen public health education, and standardize documentation practices.
