Table 1 Importance of litter effects on body weight and behavioural tests

From: Improving basic and translational science by accounting for litter-to-litter variation in animal models

Variable Reduction in σ ε 2 P-value
Locomotor activity 61% <0.001
Body weight 50% 0.003
Marbles buried 38% 0.045
Anxiety (open field) 35% 0.0504
Grooming 23% 0.116
  1. The p-value tests whether the litter-to-litter variation was significantly greater than zero. σ ε 2 is the residual (unexplained) variation.
