Long-term efficacy and impact on rehospitalization of Qishen granules in patients with hypertension and heart failure with reduced ejection fraction: a multicenter, randomized, double-blind, placebo-controlled trial protocol.
Article in Frontiers in cardiovascular medicine, 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
Background: Heart failure with reduced ejection fraction (HFrEF) represents a severe manifestation or terminal stage of various cardiac diseases. Long-term hypertension frequently leads to pathological changes such as ventricular remodeling, resulting in HFrEF. Despite continuous advancements in medications targeting hypertension complicated by HFrEF, the five-year survival rate for patients remains below 50%. Chinese Medicine (CM) demonstrates favorable long-term efficacy in managing HFrEF and reducing readmission rates. Focusing on the primary symptoms of HFrEF, we innovatively proposed the syndrome pattern "Toxic Pathogen Syndrome" and developed the effective compound formula Qi Shen Granules (QSG). This trial aims to conduct a prospective clinical study to evaluate the efficacy and safety of QSG in patients with hypertension and HFrEF. Methods: This is a multicenter, prospective, randomized, double-blind, placebo-controlled clinical trial. A total of 220 eligible participants with hypertension and HFrEF will be recruited and randomized in a 1:1 ratio to receive either QSG or placebo for 12 weeks. All participants received guideline-directed treatment for hypertension and HFrEF throughout the study period. The primary outcome is the improvement rate in plasma NT-proBNP levels from baseline to endpoint and the six-minute walk test. Secondary outcomes include echocardiographic parameters, NYHA functional class, Kansas City Cardiomyopathy Questionnaire (KCCQ), and Heart Failure Toxicity Scale. Safety measures, including liver and kidney function blood tests and adverse events, were used to assess QSG safety. We also conducted follow-up assessments at weeks 26 and 52 to evaluate patient readmission rates and the occurrence of cardiovascular adverse events. Discussion: The results of this study may establish clinical evidence supporting the therapeutic benefits and safety of QSG in the management of hypertension with HFrEF.
