Vaccination Coverage and Adherence to Scheduling in Children Aged 0 to 18 Months: Effects of COVID-19 and Age.

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
Vaccination in Peru began 50 years ago as part of the Expanded Program on Immunization (EPI), which has proven effective in saving the lives of millions of children. This research aimed to determine the coverage and adherence to the vaccination schedule in children up to 18 months of age during the period 2018-2022, including the COVID-19 pandemic lockdown, in order to assess its influence. MATERIALS AND
methodsThis was a secondary source study based on the Demographic and Family Health Survey (ENDES) of Peru, including a sample of 82,702 male and female children whose caregivers presented vaccination cards. Coverage and adherence indicators were calculated, and differences were evaluated between the pre-confinement, absolute confinement, and relative confinement periods using a chi-square test.
resultsFor almost all vaccines, coverage decreased from 2018 to 2022 (from 82.46% to 80.16% on average,
conclusionsCOVID-19 negatively influenced compliance with the vaccination schedule and adherence.
