Aggregated data for: Low-cost tissue expansion using a saline-based device shows comparable histological outcomes in a rat model

This dataset contains aggregated data extracted from the thesis and used to support the macroscopic, histomorphometric, and exploratory cost analyses reported in the manuscript "Low-cost tissue expansion using a saline-based device shows comparable histological outcomes in a rat model". Individual animal-level data were not available at the time of deposition. Data are presented as mean, standard deviation, sample size per group, p-values, and aggregated cost parameters.
