Comparison of taste detection time, total test time and taste identification thresholds between the taste solution test and the taste film kit test

Variable	Taste quality	Solution test	Film test	P value
Taste identification threshold	Sweet	2.77±0.75	3.04±0.79	0.009*
	Salty	2.14±0.69	2.45±0.64	0.002*
	Sour	2.93±0.72	3.16±0.75	0.014*
	Bitter	3.74±1.05	3.35±0.77	0.006*
Taste detection time (s)	Sweet	2.01±1.19	3.15±1.99	0.000*
	Salty	1.72±0.87	2.61±1.21	0.000*
	Sour	1.98±1.08	2.76±1.46	0.000*
	Bitter	2.72±1.63	4.03±1.67	0.000*
Total test time (min)	–	7.04±1.98	6.16±2.27	0.004*

All data are expressed as the mean±SD.

The p values were assessed using the Wilcoxon matched-pairs signed-rank test (taste identification threshold and taste detection time) or paired t-test (total test time).
