Remote Recruitment to Diversify Infant Research Participation: Lessons From the Infant Vaccine Biepository.
Article in Acta paediatrica (Oslo, Norway : 1992), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
aimTo determine whether remote recruitment, electronic consent and at-home blood collection enabled enrollment of a geographically and socioeconomically diverse infant cohort in the United States (US).
methodsWe describe the demographics of 256 infants included in this analysis, drawn from 264 enrolled in the Infant Vaccine Biorepository (December 2022-April 2026). Participants were recruited via online advertising and electronic medical record messaging. Geographic distribution was assessed using US Census regions and Rural-Urban Commuting Area (RUCA) codes. Social vulnerability was characterized using the Centers for Disease Control and Prevention (CDC) Social Vulnerability Index (SVI) at census tract and county levels, with nationwide rankings.
resultsInfants were distributed evenly across the four US geographic regions; 9% resided in rural areas. Based on nationwide census tract-level SVI rankings, 39.8% of participants fell in the medium-high or high vulnerability categories. County-level SVI rankings indicated that 57.0% of participants fell in these same categories. Participants were 78% White and 20% Hispanic; 94.1% of mothers had received at least one COVID-19 vaccine.
conclusionFully remote recruitment, consent and specimen collection enabled enrollment of infants from diverse geographic and socioeconomic backgrounds across the US. SVI and RUCA provide richer characterization of study populations than traditional demographic measures alone.
