Table 6. Reasons given by survey participants for not using tunnel handling to pick-up laboratory mice by the two main job roles (N = 259).

Participants could select multiple options therefore the options sum to >100%. Difference of > 5% in the reasons selected between Researchers and Animal Care Staff are highlighted in bold. * denotes P = 0.01.
