Median overall survival in days of age is provided for indicated animal treatment groups. p values were calculated by the log-rank test (Mantel-Cox) comparing overall survival between indicated treatment groups (reference vs. test). ^aEtOH was diluted in sterile PBS with iodine-containing contrast agent. ^bEtOH was diluted in sterile water
