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 describe adverse event following immunization or vaccination in children in Minas Gerais: 2015 to 2020, resulting from immunization errors in children from zero to nine years old.
methodsAn ecological, descriptive study with a quantitative approach, based on event notifications available in the National Immunization Program Information System.
resultsAmong the 39,903,277 doses of immunobiologicals in children aged zero to nine, administered in the state of MG, 3,259 events of types of immunization errors were recorded, around 0.008% of the total and, of these, 91.86% did not result in adverse events and 56.02% were children under one year of age. The most frequent diagnosis was application outside the recommended age (29.12%). Among the manifestations, 71.91% were local and systemic, with fever being the most common (40.85%).
conclusionThe study demonstrated that immunization errors were rare and that most of them were not associated with adverse events, which reinforces the safety of the immunization process. This undoubtedly raises reflection on the need and relevance of continuing education for health professionals.
