Survival after calling trials
Survival of 211 males was tracked daily following the conclusion of calling effort trials (sample sizes for diet type and infection cue dose included in appendix table A1).
Neither diet type (Cox proportional hazards regression:χ2 1 = 0.900; p = 0.3428) nor infection cue dose (Cox proportional hazards regression:χ2 4 = 1.371; p = 0.8492) significantly influenced survival following calling effort trials; the nonsignificant interaction between diet and infection cue (χ2 4 = 4.598; p = 0.3311) was removed from analysis.
