Use of a multistate model in survival predictions in cardiology studies.
Article in REC, interventional cardiology. 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
Introduction and objectives: Multistate models have proven to be effective tools in survival analyses. We propose modeling disease progression in interventional cardiology studies using a multistate model. Methods: The model was fitted to the PACO-PCI database including a total of 1057 elderly patients with atrial fibrillation revascularized with drug-eluting stents to assess the efficacy profile and prognosis of different antithrombotic therapies. The model defines a total of 4 states: treatment, myocardial infarction and/or revascularization, bleeding, and death, with significant factors for each transition, and was compared using a multivariate Cox model. Results: Survival factors common to both analyses were the PreciseDAPT and HAS-BLED scales, anemia, diabetes mellitus, chronic kidney disease, number of vessels treated, and left ventricular function. The multistate model also shows that after a new hemorrhage the probability of myocardial infarction and/or revascularization is influenced by the treatment of left main coronary artery disease and the transition to death from previous coronary artery bypass graft. Compared with Cox models, multistate models allow us to tell which transition in the model is influenced by each predictor. Conclusions: The results illustrate the additional advantages of multistate models in survival analyses through individual predictions for the patients based on their clinical characteristics and disease progression.
