Discrepancy between official records of the Brazilian National Immunization Program Information System and the household survey about vaccination coverage in Cubatão, São Paulo: cross-sectional study, 2023.

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
objectiveTo assess the concordance between vaccination data registered in the Brazilian National Immunization Program Information System and information in the vaccination booklets of children under 2 years of age who participated in the household survey of vaccination coverage in Cubatão, São Paulo.
methodsThis is a descriptive study comparing the doses registered in vaccination booklets with those in the Brazilian National Immunization Program Information System for children born in 2019 and 2020. Concordance was assessed regarding the doses applied and application dates recorded, using the Kappa test and the intraclass correlation coefficient.
resultsThe household survey showed that vaccination coverage targets were achieved for all vaccines in the national immunization schedule for children under 2 years of age: 90.0% for BCG and human rotavirus, and 95.0% for other vaccines. When checking the same children in the information system, coverage was below 70.0%, and in 10.0% of them the application dates were inconsistent. Approximately 24.0% of the children were not entered in the information system, despite having their vaccinations recorded in their booklets.
conclusionThe results indicate issues regarding accuracy and completeness of data from the Brazilian National Immunization Program Information System compared to vaccination booklets, highlighting challenges in vaccination records that may compromise monitoring of vaccination coverage in Cubatão.
