* Incedence rate of injury in each main occupation per 100 person

The prevalence of main occupations were significantly different between worker with and withought gig work experience (p<0.001,Chi-square test).

▽: statistically significant lower than expected value by residual analysis

▲: statistically significant higher than expected value by residual analysis
