Figure 1: SI rates according to the working years.
From: A large-scale survey on sharp injuries among hospital-based healthcare workers in China

Panel (A), SI rates according to working years. Panel (B), SI rates according to every ten working years. SI rates are expressed by incidents per 1,000 HCWs per month. Vertical axis is SI rates and horizontal axis is the working years for HCWs. Both trends in Panel A and B were statistically significant (p < 0.05).
