Impact of Text Message Reminders on Attendance at a Health Center-Based Produce Market: A Quasi-Experimental Study.
Article in Journal of general internal medicine, 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
backgroundFood insecurity is associated with adverse health outcomes and disproportionately affects low-income and minoritized communities. Mobile produce markets co-located within healthcare settings have emerged as a promising strategy to reduce food insecurity, but sustained program engagement remains a challenge.
objectiveTo evaluate the impact of bilingual text message reminders on attendance at a health center-based produce market.
designA quasi-experimental study using interrupted time series analysis of aggregate attendance data from March 2021 to 2024.
participantsPatients of a federally qualified health center with access to an on-site mobile produce market.
interventionMonthly bilingual text message reminders about the produce market, initiated in April 2024. MAIN MEASURES: Change in monthly market attendance and predictors of delayed reattendance (≥ 3 months). Logistic regression models adjusted for time-in-sample were used to estimate associations. KEY
resultsText message reminders were associated with a sustained increase in attendance (+ 80.7 individuals/month; 95% CI, 42.5-119.0). Among 2597 individuals with a ≥ 3-month gap or no return, reattendance was less likely among men (adjusted odds ratio [aOR] 0.74; 95% CI, 0.59-0.92), Medicaid enrollees (aOR 0.67; 95% CI, 0.51-0.88), and uninsured individuals (aOR 0.53; 95% CI, 0.40-0.70).
conclusionsText message outreach was associated with increased participation in a health center-based food access program. However, disparities in reattendance by insurance status suggest that text-based interventions may reinforce existing inequities, highlighting the need for multimodal outreach strategies or options for home delivery.
