Kaplan–Meier survival curves for Caenorhabditis elegans fed with varying amounts of tapuy wine or lees or fed without tapuy supplementation. A risk table showing the percentage of the population at risk is included below the Kaplan–Meier survival curves. Results of lifespan assays of three trials were pooled together to form one survival curve per experimental group. Sample sizes are n = 80 for the tapuy lees high, n = 83 for the tapuy lees low, n = 82 for the tapuy wine high, n = 77 for the tapuy wine low, and n = 82 for the no supplementation group. The concentrations of tapuy wine and lees high are 50,000 µg/mL. The concentrations of tapuy wine and lees low are 5,000 µg/mL
