  1. M (days) - median lifespan; 90% (days) - age of 90% mortality (maximum lifespan); dM (%), d90% (%), − differences between median and maximum (age of 90% mortality) lifespan of control and experimental flies, respectively; n - number of flies; *p < 0.01, FET - Fisher’s exact test (median lifespan comparison), WAT - Boschloo’s (Wang-Allison) test (maximum lifespan comparison)
