^†Interaction of specified predictors.

^aCurrent condition was dummy coded with the ‘intermittent’ pair housing condition being the reference category.

^bObservation period was dummy coded with ‘midday’ being the reference category.

^cExperimental group was dummy coded with the ‘CI’ experimental group being the reference category.

^dAge (years) was log and z-transformed, original values ranged from 4.84 to 10.77 years, mean ± standard deviation: 6.63 ± 1.72 years.

^eWeight (kg) was z-transformed, original values ranged from 4.74 to 8.72 kg, mean ± standard deviation: 6.55 ± 1.18 kg.
