Pharmacist interventions to improve hypertension management among patients with diabetes: a systematic review and meta-analysis of randomized controlled trials.
Synthesis in BMC health services research, 2025. 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
backgroundImproving blood pressure (BP) control is of major importance among patients with diabetes, due to their high risk of micro- and macrovascular complications. Community-based models of care with the involvement of pharmacists and other nonphysician healthcare providers can help manage hypertension. We aimed to estimate the effectiveness of pharmacist interventions, alone or in collaboration, on BP among outpatients with diabetes and hypertension.
methodsWe conducted systematic searches of randomized controlled trials (RCTs) assessing the effect of pharmacist interventions on BP among outpatients with hypertension and diabetes compared to usual care. The outcome was the systolic and diastolic BP change or BP control. We performed a meta-analysis with a random effects model to estimate mean differences in BP or relative risk of BP control, with 95% confidence intervals (CIs). The protocol was registered in PROSPERO (CRD42021279751) and published in an open-access peer-reviewed journal.
resultsOut of 2330 study records identified by electronic database searching, we included 12 studies in the systematic review, with 5,256 participants (control 2,906; intervention 2,350), published between 2002 and 2022. In comparison with usual care, mean systolic and diastolic BP were reduced after pharmacist interventions by -7.2 mmHg (95% CI: -12.5 to -1.9; I2 = 87%) and − 4.1 mmHg (95% CI: -6.9 to -1.4; I2 = 0%), respectively. BP control was improved after pharmacist intervention (relative risk: 1.76, 95% CI: 1.39 to 2.24; I2 = 50%). Analyses restricted to relatively large or high-quality studies yielded consistent but slightly lower estimates.
conclusionPharmacist interventions improve BP control in patients with diabetes and hypertension. PROSPERO REGISTRATION NUMBER: CRD42021279751.
