Impact of the COVID-19 lockdown on routine childhood vaccination coverage rates in Catalonia (Spain): a public health register-based study.
Article in Public health, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers, 1 of them a synthesis that pooled it.
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
objectiveThe aim of this study was to determine the impact of the lockdown measures adopted during the COVID-19 pandemic on routine childhood vaccination coverage rates in Catalonia (Spain) and to estimate its recovery once the progressive return to 'normalcy' had begun. STUDY
designWe conducted a public health register-based study.
methodsRoutine childhood vaccination coverage rates were analysed in three periods: a first pre-lockdown period (from January 2019 to February 2020), a second lockdown period with full restrictions (from March 2020 to June 2020), and, finally, a third post-lockdown period with partial restrictions (from July 2020 to December 2021).
resultsDuring the lockdown period, most of the coverage rates remained stable, concerning the pre-lockdown period; however, when comparing the vaccination coverage rates in the post-lockdown period to the pre-lockdown period, we observed decreases in all types of vaccines and doses analysed, except for coverage with the PCV13 vaccine in 2-year-olds, which experienced an increase. The most relevant reductions were observed in measles-mumps-rubella and diphtheria-tetanus-acellular pertussis vaccination coverage rates.
conclusionsSince the beginning of the COVID-19 pandemic, there has been an overall decline in routine childhood vaccine coverage rates, and the pre-pandemic rates have not yet been recovered. Immediate and long-term support strategies must be maintained and strengthened to restore and sustain routine childhood vaccination.
