	2b	When leveraging experimental designs where a double-blind is possible, use a double-blind
Control measures
	3b	Report whether participants were provided with a strategy
Outcome measures
Brain	5a	Report neurofeedback regulation success based on the feedback signal
	5b	Plot within-session and between-session regulation blocks of feedback variable(s), as well as pre-to-post resting baselines or contrasts
	5c	Statistically compare the experimental condition/group to the control condition(s)/group(s) (not only each group to the baseline measures)
Behavior	6a	Include measures of clinical or behavioral significance, defined a priori, and describe whether they were reached
	6b	Run correlational analyses between regulation success and behavioral outcomes
