Comparison of imaging findings of 714 symptomatic and asymptomatic temporomandibular joints: a retrospective study

Table 2 Comparison between the symptomatic and asymptomatic side of TMJ

	Asymptomatic (n = 354)	Symptomatic (n = 360)	t	CI (95%)		P
	Asymptomatic (n = 354)	Symptomatic (n = 360)	t	Lower	Upper	P
Age	25.34 ± 10.85	26.88 ± 11.50	− 1.838	− 3.182	0.105	0.066
AJS	2.53 ± 0.81	2.77 ± 0.87	− 3.867	− 0.367	− 0.120	0.000
SPS	2.96 ± 0.93	2.82 ± 0.87	2.080	0.008	0.273	0.038
PJS	2.35 ± 0.81	2.33 ± 0.88	0.331	− 0.103	0.144	0.741

Mean age and joint spaces were described by mean ± standard deviation. An Independent-samples T test was performed for the comparison of mean age, AJS, SPS, and PJS between the symptomatic and the asymptomatic side. CI: confidence interval; AJS: anterior joint space; SJS: superior joint space; PJS: posterior joint space. Significant difference was set at < 0.05
