Summarized Longitudinal Echocardiography Dataset (PKN2 cKO vs Control)

This file contains the structured longitudinal echocardiography dataset used for statistical analysis of cardiac function in PKN2 cardiomyocyte-specific knockout (cKO) and control mice. Each row corresponds to one animal at one time point and includes genotype, animal identifier, age, and measured parameters such as fractional shortening (FS), left ventricular internal diameters (LVIDd, LVIDs), and wall thickness measurements (LVPWd, IVSd). The dataset is formatted for mixed-effects modeling with repeated measurements nested within animals.
