i Lethal time (LT50 and LT99) values with 95% fiducial limits (FL).
All values are expressed in mins. LT values within each column or category (i.e., LT50 or LT99) that are not connected by the same letter are significantly different as their confidence intervals do not overlap with the number “1” [37].
