Correlation analysis between the effectiveness of computerized/VR training programs on emotion recognition in ASD samples.

	All available studies	HFA subgroup	Mixed ASD subgroup	VR training program	non-VR Computerized training programs
Age	r = −0.052, p = 0.78, n = 32	r = 0.47, p = 0.066, n = 16	r = −0.03, p = 0.92, n = 15	r = 0.05, p = 0.85, n = 17	r = 0.11, p = 0.7, n = 15
IQ	r = 0.176, p = 0.584, n = 12	r = 0.28, p = 0.65, n = 5	–	–	r = 0.29, p = 0.49, n = 8

r indicates the correlation coefficient and n shows the number of included studies for correlation analysis. The dashed line indicated that there was not enough data (n ≤ 3) for calculating a reliable correlation coefficient.
