Effectiveness of a CDSS and Internet of Things-based comprehensive hypertension management system in primary health care settings: study protocol for the CATCH Trial.
Article in Trials, 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
backgroundCardiovascular and cerebrovascular diseases are the leading causes of death in the Chinese population, and hypertension is one of the key risk factors. However, the blood pressure control rate of hypertensive patients is low at present. The main factors include the limited capacity of primary care workers and poor self-management among hypertensives. The purpose of this program is to use a clinical decision support system (CDSS) and an Internet of Things-based comprehensive hypertension management system (CATCH) to provide decision support for the diagnosis and treatment of hypertension for primary care clinicians and to improve the standardisation of the diagnosis, monitoring, treatment, and continuous management of hypertension among them.
methodsThis study is a stepped wedge cluster randomised controlled trial conducted in 12 community health centres in the Third People's Hospital of Longgang District, Shenzhen City, China. All participants who are registered in the community and with systolic blood pressure ≥ 140 mmHg and/or diastolic blood pressure ≥ 90 mmHg at the screening clinic will be asked to participate in the study. The intervention is a CATCH composite of a hypertension auxiliary decision-making module, clinical diagnosis and treatment knowledge education system, and quality control system. All 12 clusters will be divided into 4 clusters and 5 stages according to a randomised method, with each stage lasting 3 months, ensuring that the entire trial will be completed within 12 months. DISCUSSION: The CATCH trial uses CDSS and IoT to improve hypertension management in primary care. This stepped wedge trial enhances guideline adherence and patient outcomes through remote monitoring and quality control. All centres receive the intervention, ensuring equitable access to it. Results will guide future hypertension strategies.
trial registrationThe trial was registered at the National Medical Research Registration and Record Filing Information System of China in December 2024, was retrospectively registered at the Chinese Clinical Trial Registry (ChiCTR) (Registration number: ChiCTR2500098845) https://www.chictr.org.cn/.
