A Medication Synchronization Program and Blood Pressure Levels in a Community Pharmacy: Protocol.
Article in JMIR research protocols, 2019. 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
backgroundThe lack of adherence to prescribed antihypertensive medication occurs in 50% of patients and leads to poor health outcomes and increased medical costs. Consistent use of antihypertensive medications among patients with hypertension is essential to the reduction of short- and long-term cardiovascular complications. Strategies to improve medication adherence include syncing prescription medications in the pharmacy, which allow patients to retrieve chronically prescribed medications in one visit. The adoption of medication synchronization has been shown to improve adherence to medications; however, there is a lack of data showing if the intervention reduces blood pressure and improves long-term health outcomes.
objectiveThis study aims to determine the association between participation in an appointment-based medication synchronization service and blood pressure levels among patients on antihypertensive medications.
methodsThis longitudinal prospective cohort study will observe changes in blood pressure among individuals in a medication synchronization program and those in a usual care group. Patients on at least two antihypertensive medications and four total medications have been recruited to participate in the study. All participants will be required to have at least a 6-month history of filling prescriptions at the pharmacy prior to enrollment in the study. Based on an estimated standard deviation of 14 mmHg, a sample size of 70 participants provides approximately 80% power with a two-sided .05 significance to detect a difference of 9 mmHg blood pressure between the two cohorts.
resultsAs of the publication of this paper, patients are completing final blood pressure visits at the pharmacy and medication data are being collected from the pharmacy. Once patients complete all blood pressure visits, data analysis will begin.
conclusionsThis study will link medication synchronization and changes in blood pressure levels among individuals with hypertension. This study will provide preliminary data for a randomized clinical trial that will assess the impact of medication synchronization on blood pressure.
