^aSignificance level could not be calculated
^bChi-square test could not be calculated because expected cell frequencies of one or more cells were less than 5
^c*p ≤ .05 (significant), **p ≤ 01 (highly significant), ***p ≤ .001 (highly significant)
^dφ (Phi) ≤ .10 (small effect), φ = .30 (moderate effect), φ ≥ .50 (large effect)
^eThe indication “wipe disinfection of the work surface” was not considered in the calculation, as it was not required for non-COVID-19 wards
