Both genotypes were subjected to starvation and compared to controls fed ad libitum. Their survival was tracked until 100% mortality was reached. Under starvation SOD1-nulls lived significantly longer than SOD+ controls (Kaplan-Meier log-rank, Chi-square: 87.956, p<0.0001 mean SOD1-null lifespan: 2.84 days, SE: 0.062, mean control lifespan: 1.94 days, SE: 0.049).
