Oleic acid (OA) detection threshold frequencies in obese and normal-weight groups^†

(Numbers of subjects and percentages)

	Obese (n 50)		Normal weight (n 50)
OA concentrations (mmol/l)	n	%	n	%
0⋅018	1	2	16	32*
0⋅18	3	6	15	30*
0⋅37	4	8	8	16*
0⋅75	13	26	6	12*

^*Significant (P < 0⋅05) difference in the frequency of detection of OA compared with the obese subjects (χ² test).

^†Subjects were presented with each series of concentrations in ascending order, from the lowest (0⋅018 mmol/l) to the highest (12 mmol/l) concentration.
