They're both diapers. 0 is urinary and fecal incontinence. 1 is urinary incontinence that can't be managed by anything less than a diaper.

LI's artwork often mentioned field changes, but he never explained the need for another person to change the wearer.

So level 1 is diapers and level 0 is? Diapers + mandatory caregiver?
