Publication bias assessment of the fear learning processes using Egger’s regression test (p value) and the Trim and Fill analysis (imputed missing studies)

Fear learning process	Egger’s regression test	Trim and Fill analysis
Acquisition learning to cue	0.468	12
Acquisition learning to context	0.466	0
Cued fear expression after acquisition learning	0.448	7
Contextual fear expression after acquisition learning	0.15	26
Extinction learning to cue	0.016	0
