Timing of wound closure (immediate vs delayed)

Adverse events ‐ superficial infection · adults with open long bone fractures of the upper and lower limbs

It is very uncertain whether timing of wound closure (immediate changes adverse events ‐ superficial infection compared with delayed) (very low certainty).
