Table 2 Comparison between the three patients’ groups and control group regarding different clinical characteristics

Different clinical characteristics	CTS group (n = 57 hands from 36 patients) ^b, mean ± SD	TF group (n = 25 hands from 22 patients), mean ± SD	CTS with TF group (n = 28 hands from 24 patients) ^b, mean ± SD	Control group (n = 60 hands from 46 apparently healthy volunteers), mean ± SD	Test of significance	P
Side (right/left) ^a	29 (50.9) / 28 (49.1)	16(64.0) /9(36.0)	19(67.9) /9(32.1)	34(56.7) /26(43.3)	(X²) 2.702	0.440
Dominant hand ^a	30 (52.6)	18 (72.0)	19 (67.9)	37 (61.7)	(X²) 3.518	0.318
Duration of complaint (months)	12.87 ± 9.93 ^{c d}	12.24 ± 8.58 ^{d e}	8.07 ± 6.07 ^{c e}	NA	(K) 7.411	0.025*
Patient global assessment of hand symptoms (VAS)	5.10 ± 2.86 ^{d f}	4.80 ± 2.10 ^{d g}	6.96 ± 1.64 ^{f g}	NA	(K) 12.903	0.002*
Patient global assessment of effect of hand symptoms on function and quality of life (VAS)	4.45 ± 2.82 ^{f d}	3.26 ± 2.24 ^{d g}	6.35 ± 2.16 ^{f g}	NA	(K) 19.268	≤0.0001*

VAS, visual analogue scale; CTS, carpal tunnel syndrome; n, number of hands; SD, standard deviation; TF, trigger finger; K, value of Kruskal–Wallis test; X², value of Pearson’s chi-squared test
*P is significant at < 0.05.
^aData are presented as (number (percentage)) of hands.
^bThere were seven patients with bilateral CTS in which there was TF in one hand and not in the other. These seven patients were presented in the CTS group regarding their hands with only CTS and presented again in CTS with TF group regarding their hands with CTS and TF.
^cDuration of complaint was significantly longer in the CTS group versus the CTS with TF group (P < 0.05).
^dNo significant difference between the CTS group and the TF group (P > 0.05).
^eDuration of complaint was significantly longer in the TF group versus the CTS with TF group (P < 0.05).
^fPatient global assessment of hand symptoms (VAS) and patient global assessment of effect of hand symptoms on function and quality of life (VAS) were significantly higher in the CTS with TF group versus the CTS group (P < 0.05).
^gPatient global assessment of hand symptoms (VAS) and patient global assessment of effect of hand symptoms on function and quality of life (VAS) were significantly higher in the CTS with TF group versus the TF group (P < 0.05).
