Automated Text Message-Based Program to Improve Uncontrolled Blood Pressure in Primary Care Patients: A Randomized Clinical Trial.
Trial report in Journal of general internal medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05571410 (Program Design Hypertension Chat Bot Pilot Study With the Primary Care Service Line), which is not on this map. Cited by 4 papers.
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.

Abstract
backgroundSuboptimal control of BP is common, although safe and effective treatments are widely available. Conventional management relies on office visits, but this can be an inefficient path to medication optimization.
objectiveTo assess the effectiveness of an intensive, 6-month remote BP management program among patients with uncontrolled hypertension.
designA two-arm randomized clinical trial which ran from January to July 2023 at two primary care practices with an in-clinic BP measurement at the end of the intervention.
participantsEstablished adult patients (ages 21-80) of study practices with uncontrolled hypertension (two measurements > 140/90 in the prior 12 months) and an active prescription for at least one anti-hypertensive agent.
interventionParticipants received automated text messages prompting them to check their BP weekly for 6 months. An RN and APP monitored BP data entered by the participant. The automated platform escalated any out-of-normal range readings or needs to the program staff. MAIN MEASURES: The primary outcome was change in SBP from baseline to the end-of-study measurement. Enrollment and engagement measures were collected for the intervention arm. KEY
resultsOf the 300 participants, the mean (SD) age was 63 (± 12.2) years; 133 (44.3%) were male and 167 (55.7%) were female; 154 (51.5%) self-identified as Black and 120 (40.1%) White; and 119 (39.7%) were insured by Medicare and 41 (13.7%) by Medicaid. The change in SBP at 6 months among those who completed the end-of-study measurement was - 14.66 mmHg (95% CI - 19.95, - 9.36) in the intervention arm and - 10.87 mmHg (95% CI - 18.04, - 3.69) in the control arm (p = 0.39). Within the intervention arm, 97 participants (64.7%) completed all enrollment steps, and these participants submitted BPs 72.8% of the weeks. Participants in the intervention arm had a greater number of medication changes (0.81 vs 0.57 in the control arm, p = 0.01) over the study period.
conclusionsIn this randomized clinical trial of a 6-month automated text messaging program, there was no significant difference in the change in SBP among participants in each arm.
