Text Messaging Intervention for Postpartum Alcohol Use: Micro-Randomized Trial Supports Feasibility, Acceptability, and Maternal Message Preference.
Trial report in Journal of studies on alcohol and drugs, 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
objectiveThis pilot micro-randomized trial (MRT) evaluated the feasibility of the MRT design and compared the acceptability and preliminary impacts of drinking-focused and maternal-focused text messages to inform the development of a tailored, just-in-time adaptive text messaging intervention for postpartum at-risk alcohol use.
methodPostpartum mothers (
resultsCompliance rates for all survey types exceeded 70%, except for optional night surveys. Participants reported a low burden associated with the MRT. Participants were more likely to rate maternal-focused messages as helpful and evoking positive feelings compared with drinking-focused messages. A significant effect of receiving an intervention message (vs. no message) was found for drinking self-efficacy (DSE), with those who received a message reporting higher DSE than those who received no message, and no difference between message types. Significant time-by-condition interactions revealed that the effect of maternal messages decreased over time, whereas DSE increased over time for the control condition.
conclusionsFindings support the feasibility and acceptability of the MRT design in postpartum mothers with at-risk drinking histories and inform the development of a tailored text messaging intervention for this population.
