1 · What the graph read from 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.

2 · The registry

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 authors evaluated factors contributing to coronavirus disease 2019 (COVID-19) vaccine hesitancy among pregnant and postpartum women to inform vaccine scale-up strategies.

methodsThis observational study utilized data from pregnant and postpartum women attending four public maternal child health (MCH) clinics in Western Kenya. From October 2020 to July 2022, nurses assessed COVID-19 vaccine hesitancy, defined as reporting "unlikely" or "very unlikely" to the question, "If a vaccine for COVID-19 were available today, what is the likelihood that you would get vaccinated?"

resultsAmong 1023 women (235 pregnant, 788 postpartum), 20% reported worsened MCH care during the pandemic and most (92%) perceived themselves or family members to be at risk for COVID-19, yet 54% of women reported COVID-19 vaccine hesitancy. Vaccine hesitancy was more frequent among women reporting worsened MCH care (P < 0.001) since the pandemic and those who did not trust the government as a source of COVID-19 information (P = 0.016). Over the 2-year period, willingness to receive the vaccine almost doubled (38% to 71%, P < 0.001).

conclusionsOur findings suggest that sustaining access to quality MCH services may decrease COVID-19 vaccine hesitancy. Willingness to receive the vaccine doubled over the 2-year period in our cohort, suggesting increased trust for use and acceptance in the unique context of the pregnancy/postpartum period.
