Longitudinal Trends in Vaccine Hesitancy in a Cohort of Mothers Surveyed in Washington State, 2013-2015.

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
Parents who refuse or delay vaccines because of vaccine hesitancy place children at increased risk for vaccine-preventable disease. How parental vaccine hesitancy changes as their children age is not known. In 2015, we conducted a follow-up survey of 237 mothers enrolled in a 2-arm clinic-level cluster randomized trial (n = 488) in Washington State that was completed in 2013. We surveyed mothers at their baby's birth, age 6 months, and age 24 months using a validated measure of vaccine hesitancy. Both mean hesitancy scores (mean 4.1-point reduction; 95% CI, 2.5-5.6; P = .01) and the proportion of mothers who were vaccine hesitant (9.7% at baseline vs 5.9% at 24 months; P = .01) decreased significantly from child's birth to age 24 months. Changes from baseline were similar for first-time mothers and experienced mothers. Individual item analysis suggested that the decrease may have been driven by increases in maternal confidence about the safety and efficacy of vaccines. Our results suggest that hesitancy is a dynamic measure that may peak around childbirth and may remit as experience with vaccines accumulates.
