PPE, Personal protective equipment; PROD, PPE-related occupational dermatosis.
Each subgroup of PPE is further assigned 1 or more subscripts (a-d). PPE subgroups sharing 1 or more subscripts do not have a statistically significant difference in the prevalence of PROD (P > .05). PPE subgroups that do not have a subscript in common between them have a statistically significant difference in the prevalence of PROD (P ≤ .05). For example, the prevalence of PROD among those wearing disposable face shields (headband) was significantly different from those wearing UVEX goggles (as their subscripts are dissimilar, ie, “a” vs “b”). Conversely, there is no statistically significant difference when comparing the prevalence of PROD between disposable face shield and other protective eyewear subtypes as they all contain “a” in their assigned subscripts.
Percentages are expressed as a proportion of the number of HCWs using the same model of PPE constituent.
