The role of Tei index as an early predictor for evaluating experimental uremic cardiomyopathy model.
Article in BMC nephrology, 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
backgroundUremic cardiomyopathy (UCM) remains the leading cause of cardiovascular mortality in patients with end-stage renal disease (ESRD). Experimental animal models serve as essential tools for elucidating the potential mechanism underlying UCM. However, experimental UCM models are often challenged by inter-individual variability and inconsistent success rates. Reliable phenotypes are not guaranteed by current animal models of UCM. In this study, Tei index from echocardiography was investigated for its potential value in construction of murine UCM model based on 5/6 nephrectomy (Nx).
methodsComprehensive echocardiographic assessment, measurement of blood pressure and serum creatinine, histological analysis, and quantitative polymerase chain reaction (qPCR) were performed to reveal the relationship between Tei index and construction of UCM model.
resultsThe Tei index was significantly elevated in Nx mice despite preserved cardiac function and structural integrity at 8 weeks post-nephrectomy. A longitudinal follow-up to the 12
conclusionsThis study validates the Tei index as a sensitive and non-invasive parameter for the early evaluation and prediction of UCM murine model induced by 5/6 nephrectomy.
