Table 3. Summary of secondary outcome measures, split by condition.

		Inward	Straight	Outward
Micro-drinking behaviours	Mean sip size (ml)^a	22.00 (16.50 to 30.00)	18.33 (12.11 to 25.91)	19.41 (15.00 to 30.75)
	Mean sip duration (sec)^a	2.14 (1.72 to 2.89)	1.94 (1.47 to 2.72)	1.93 (1.65 to 2.80)
	Mean interval duration (sec)^a	17.71 (11.77 to 29.46)	19.15 (11.26 to 38.34)	15.35 (11.76 to 23.50)
Perceptual measures	Bias in midpoint estimate (ml)^b^, ^c	-2.27 (21.05)	-3.00 (11.42)	-15.92 (15.95)
Perceptual measures	Drink enjoyment (1–10)^b	7.02 (1.65)	7.00 (1.68)	7.18 (1.66)

Note.

a. Due to positive skew in all micro-drinking behaviours, these values given are Mdn (IQR).

b. Drink enjoyment and bias in midpoint estimation are M(SD).

c. 0ml reflects 0 bias in estimation, negative values reflect underestimation of true midpoint, positive values reflect overestimation of true midpoint.
