Direct Digital Referrals From Prenatal Care and WIC Enrollment Among Pregnant Individuals: A Randomized Clinical Trial.
Trial report in JAMA network open, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06311799 (Advancing Health Equity by Integrating Social-Clinical Models During Pregnancy), which is not on this 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.

Abstract
Importance: The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) has a strong evidence base for improving perinatal outcomes, but less than half of eligible women enroll. Objective: To assess whether WIC enrollment is improved with direct digital referrals from prenatal care to WIC and/or a registered dietitian nutritionist (RDN) compared with usual care. Design, Setting, and Participants: In this 4-arm randomized clinical trial, pregnant participants were enrolled in 2024 and followed up for 6 months in a large integrated health system in Pennsylvania. Pregnant participants who met WIC income eligibility were recruited, and 1539 potential participants were identified through the electronic health record (EHR) and sent recruitment materials. Data were analyzed from April 29, 2024, to June 11, 2025. Interventions: Four models were compared, and individuals in all models received usual prenatal care. Model 1 provided patients with WIC written information. Model 2 provided patients with a direct digital referral to WIC. Model 3 provided WIC written information plus a digital referral to an RDN for telehealth counseling (1 session monthly for 6 months). Model 4 provided a combination digital referral to WIC and RDN. WIC and RDNs contacted participants after receiving referrals to arrange care. Main Outcomes and Measures: The primary outcome was measure of the difference in WIC enrollment via participant survey at 6-month follow-up. Results: Of 514 pregnant participants who completed screening, 140 were ineligible and 134 were not interested. Of 240 eligible, consenting participants (mean [SD] age, 29.2 [6.1] years; mean [SD] gestational age, 17.8 [11.1] weeks), 202 had outcome data. Randomization to digital WIC referral models increased enrollment (models 2 and 4: 78% [80 of 103]) vs no digital referral (models 1 and 3: 65% [64 of 99]) (P = .04). Randomization to RDN (models 3 and 4: 78% [76 of 97]) also increased enrollment vs no RDN (models 1 and 2: 65% [68 of 105]) (P = .03). Compared with model 1 where WIC enrollment was 54% (27 of 50), enrollment was significantly higher in other models (model 2: 75% [41 of 55]; model 3: 76% [37 of 49]; model 4: 81% [39 of 48]; all P = .03). Conclusions and Relevance: In this randomized clinical trial of pregnant individuals, both digital WIC referral and RDN referral improved WIC enrollment, offering scalable strategies to improve perinatal health.
