Values in square brackets represent the 95 % confidence intervals for the estimated median lethal time; n/a, time point not tested; n/a¹, denotes estimate nor applicable because the survival function did not reach 0.5, therefore there is not a median value estimate; ∞, infinity, the survival function did not reach the corresponding to 95 % limit value
