Impact of COVID-19 pandemic on vaccination against meningococcal C infection in Brazil.
Article in Vaccine: X, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
Objective: Analyzing the impact of COVID-19 pandemic on meningococcal C conjugate vaccination in Brazil. Methods: Ecological study, based on interrupted time series, carried out with data collected through the Information System of the National Immunization Program (IS-NIP). Collected data refer to the number of meningococcal C conjugate vaccine doses administered from March 2019 to December 2020. Results: In total, 14,832,054 meningococcal C conjugate vaccine doses were administered throughout the investigated period; 66.30% of them, from March 2019 to February 2020 and 33.70%, from March to December 2020. Statistically significant steps were observed, i.e., the COVID-19 pandemic had negative impact on the number of MenC vaccine doses administered in the North and South regions (26,98% and 41.47%, respectively) and in the eleven Brazilian States. Conclusion: The current study has shown that the COVID-19 pandemic had negative impact on the number of MenC vaccine doses administered in the Northern and Southern Brazil, and in eleven Brazilian states. Among all challenges experienced during the COVID-19 pandemic, one finds reduced MenC vaccine coverage, which, consequently, may lead to increased meningococcal infection rates in Brazil.
