Correlation of clinical anthropometric parameters of AIS patients with mRNA expression of melatonin receptor MT1 and MT2. The AIS patients were divided into groups according to their mRNA expression level of melatonin receptor MT1 or MT2 using the minimum value of normal controls as the cut-off point.

Melatonin receptor MT1 (n = 38)
Group	Normal expression (n = 32)	Low expression (n = 6)	p-value
z-score of
BW	−0.136 ± 0.98	−0.070 ± 0.62	0.875
BMI	−0.429 ± 0.98	−0.384 ± 0.67	0.915
Arm span	0.412 ± 0.92	0.471 ± 0.28	0.768
Expression of mRNA (Log (relative quantification))	−0.311 ± 0.18	−0.751 ± 0.078	<0.01
Age	15.3 ± 2.1	15.2 ± 1.5	0.940
Melatonin receptor MT2 (n= 38)
Group	Normal expression (n= 27)	Low expression (n= 11)	p-value
z-score of
BW	−0.223 ± 0.83	0.112 ± 1.13	0.318
BMI	−0.405 ± 0.83	−0.464 ± 1.18	0.861
Arm Span	0.238 ± 0.79	0.870 ± 0.86	0.036 *
Expression of mRNA (Log (relative quantification))	−0.367 ± 0.72	1.311 ± 0.21	<0.01
Age	15.1 ± 1.9	15.7 ± 2.0	0.414

Their anthropometric parameters [body weight (BW), body mass index (BMI) and arm span] were compared by Student’s t-test,

^*p < 0.05. All data were expressed as the mean ± SD.
