AAT: animal-assisted therapy, N: number of analyzed sessions, M: mean (absolute), SD: standard deviation, rate time: rate per 100 seconds, rate input: rate per 100 tactile inputs, IRR: Incident Rate Ratio, CI: confidence interval, Model 1: therapy type as fixed effect, Model 2: therapy type and time as fixed effect, Model 3: therapy type, time and log tactile input as fixed effect,

*statistically significant,

⁺ log of the time when eyes were observable was used as offset to analyze eye movement.
