Background: The global rise of obesity and its association with cardiovascular risk factors (CVRF) have highlighted connection to chronic heart failure (CHF). Paradoxically, obese CHF patients often experience better outcomes, a phenomenon known as the ‘obesity paradox’. This study evaluated paradox’ within large cohort in Germany explored how varying degrees affect HF outcome. Methods: Anonymized health claims data from largest German insurer (AOK) for years 2014–2015 were utilized analyze...

The one-sample log-rank test is the preferred method for analysing outcome of single-arm survival trials. It compares distribution patients with a prefixed reference curve that usually represents expected under standard care. However, classical tests assume known, ignoring it frequently estimated from historical data and therefore susceptible to sampling error. Neglecting variability can lead an inflated type I error rate, as shown in previous paper. Here, we propose new allows account...
