Table 5.

Logistic regression was used to evaluate the effect of wrist posture on wrist injury by gender and length of service.

Variable	Wrist Injury OR (95% CI) *
	Working age ≤5		Working age >5
	Male	Female	Male	Female
Whether the wrist is often bent up/down at work	1.90 (1.69, 2.15)	1.92 (1.62, 2.27)	2.22 (1.87, 2.64)	1.89 (1.58, 2.25)
Whether the wrist is often placed on the edge of a hard, angular object	1.67 (1.54, 1.82)	1.43 (1.26, 1.62)	1.50 (1.32, 1.70)	1.40 (1.23, 1.61)
Do you need to pinch/grasp objects/tools with your hands during work	1.71 (1.46, 2.00)	1.62 (1.33, 1.98)	1.89 (1.53, 2.32)	1.68 (1.36, 2.06)
Above shoulder level	1.14 (1.03, 1.25)	1.18 (1.01, 1.39)	1.19 (1.03, 1.36)	0.92 (0.77.1.10)
Whether the wrist needs to be bent for a long time	1.89 (1.73, 2.07)	2.07 (1.80, 2.37)	1.8 (1.57, 2.06)	1.72 (1.48, 2.00)
