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 and compare vaccination coverage among children born in 2017-2018 in São Paulo and Campinas, according to the Vaccination Coverage Survey (ICV 2020) and the National Immunization Program Information System (SI-PNI).
methodsICV 2020 analyzed vaccination card records. Coverage was calculated and compared to doses recorded on the SI-PNI, divided by the target population.
resultsIn São Paulo, according to ICV, in 2017 only BCG (91.7%; 95%CI 87.0;94.7) and rotavirus first dose (90.6%; 95%CI 86.5;93.5) achieved the goals; in 2018, BCG (93.4%; 95%CI 89.5;95.8), rotavirus first dose (90.5%; 95%CI 85.3;94.0), pneumococcal first dose (95.3%; 95%CI 91.7;97.4), meningococcal C first dose (95.1%; 95%CI 91.5;97.2) and pneumococcal second dose (95.0%; 95%CI 91.4;95.0). In Campinas, only BCG achieved the target in 2017 (93.0%; 95%CI 88.8;95.7) and none in 2018. According to the SI-PNI, no vaccine achieved the target in either city.
conclusionVaccination coverage was lower than expected and more precise estimates are necessary for adequate monitoring of childhood vaccination status.
