||a) Our method of data collection began
with a questionnaire format to extract subject information. The questions captured
demographic information, hand and nail care, gloving practices, lotion use and the overall
condition of the hands.
b) Throughout the study we collected information using three
measurement tools: the VSS (which visual scoring of the skin), Erythema grading scales and
HSA (hand skin assessment) all of which are correlated with objective measures of the
skin. The VSS and Erythema scales were measured by the study investigators and the HSA was
completed by the subjects themselves.
