Screening optimal target populations with symptomatic bradyarrhythmia for pharmacotherapy: a discriminant analysis pilot study.
Article in Journal of traditional Chinese medicine = Chung i tsa chih ying wen pan, 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
objectiveTo screen the target population with symptomatic bradyarrhythmia for pharmacotherapy.
methodsThis study use database from clinical trial that use Yuanjiang decoction, a traditional Chinese medicinal prescription. Eligible participants were recruited and treated with Yuanjiang decoction (composed of 6 Chinese herbal medicines), 200 mL twice daily. Cross-contingency analysis, logistic regression analysis, interaction analysis, discriminant analysis and 10-fold cross validation methods were used to establish discriminant model.
resultsThis study concluded that the clinical treatment of bradyarrhythmia has a clear effect. Low minimum heart rate, high maximum heart rate are risk factors that affect the efficacy. Patients with only one comorbid disease did not significantly affect the efficacy, but patient with two or more diseases of coronary heart disease, hypertension, paroxysmal atrial fibrillation, premature ventricular contraction and premature atrial contraction at the same time did not have a good effect. Using the discriminant analysis method to establish a efficacy prediction model, y = 0.07 X 1 + 0.16 X 2 - 0.65 X 3 - 1.12 X 4 - 0.71 X 5 - 0.75 X 6 - 0.91 X 7 (X1 = 24 h mean heart rate, X2 = minimum heart rate, X3= coronary heart disease, X4 = paroxysmal atrial fibrillation, X5 = premature ventricular contraction, X6= sinus block, X7 = atrioventricular block).
conclusionOur model based on the clinical features of patients with bradyarrhythmia. Should be useful aid for predicting pharmacotherapy response and could screen the optimal pharmacotherapy target.
