Caribbean and South American team-based strategy to control hypertension (CATCH): Rationale and study design of a cluster randomized trial.
Article in American heart journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05405920 (Implementing and Scaling Up a Team-based Care Strategy for Hypertension Control in Colombia and Jamaica), which is not on this map. Cited by 1 paper.
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.

Abstract
rationaleHypertension disproportionately affects populations in low- and middle-income countries (LMICs), especially in Latin America and the Caribbean, due to its high prevalence and low control rate. PRIMARY HYPOTHESIS: To close the knowledge-practice gap for blood pressure (BP) control, we are assessing the effectiveness and implementation of a team-based care strategy for BP control in primary care clinics in Colombia and Jamaica.
designThe Caribbean and South American Team-based Strategy to Control Hypertension (CATCH) study is a cluster randomized trial using an effectiveness-implementation hybrid type-2 design. Clinics were randomly assigned to a team-based strategy or a provider-training strategy to implement current hypertension guidelines. The team-based strategy includes healthcare team training, care coordination, task sharing, BP audit and feedback, home BP monitoring, health coaching, single-pill combination therapy, and increased medication access. The primary clinical effectiveness outcome is difference in mean change of systolic BP from baseline to 18 months between randomized groups. The primary implementation outcome is a composite fidelity score to key implementation strategy components. SITES: CATCH is conducted in 40 primary care clinics in Jamaica and Colombia. ENROLLMENT: Between February 2023 and August 2024, we recruited 1,707 participants, exceeding our planned enrollment. The planned sample size of 1,680 (42 patients per each of 40 clinics) has 90% statistical power to detect a 6.0 mm Hg difference in mean systolic BP change assuming 85% follow-up and a 2-sided significance level of 0.05. CURRENT STATUS: In follow-up
conclusionsCATCH will provide evidence on effectiveness and implementation of a team-based care strategy to improve hypertension control in real-world, primary care settings. If proven effective, this approach can be scaled up in primary care throughout low- and middle-income countries (LMICs). CLINICAL
