Pair-wise comparisons over all treatments for the survival analysis through week one and through week two are presented. Average hedges’ g for days 1 through 7 and 1 through 14 of the experiment are also presented with positive values representing increased survival as compared to the unirradiated control or sucrose irradiated treatments. The comparisons for the ethanol, lager, and TMG treatments are presented as being positive if the ethanol treatment group survives better (Ethanol vs. Lager, and Ethanol vs. TMG) or that the lager shows higher survival (Lager vs. TMG).
