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 estimate the yellow fever vaccination coverage and describe the knowledge, attitudes and practices (KAP) of the population residing in São Sebastião, Federal District, Brazil, after confirmation of a non-human primate epizootic event in the region.
methodsCross-sectional study consisting of two surveys, a vaccination coverage survey and a KAP survey, between November and December 2020. Probabilistic cluster sampling (30x7) was adopted. Individuals with the yellow fever vaccine recorded in an immunization record or in the National Immunization Program Information System were considered vaccinated. Complex analysis and descriptive statistics, with absolute and relative frequencies, measures of central tendency and accuracy were used. The KAP study employed analytical statistics, adopting prevalence ratio as measure of association and 95% confidence intervals (95%CI).
resultsIn total, 210 interviews were conducted. Vaccination coverage was 54.3% (95%CI 47.70; 60.90), with 93.9% of the records obtained from the immunization record. Of the participants, 63.8% were female and 60.0% self-declared as brown. Regarding the KAP component, 70.0% presented inadequate knowledge, 87.1% presented adequate attitudes and 54.3% presented adequate practices. The prevalence of adequate attitudes among people with adequate knowledge was 11.10 times higher than among those with inadequate knowledge.
conclusionThe study provided a description of the yellow fever vaccination coverage and KAP. The coverage found was below the 95.0% target established by the National Immunization Program, providing inputs that can support health surveillance and vaccination promotion initiatives.
