Table 1. Comparison between investigator- and self-reading of SLS patch test reactions for each subject.

Cases of disagreement are marked in grey. Results of the detailed scoring from investigator reading are presented for each different SLS-concentrations used in the provocation. Scoring key: “(+)” = barely perceptible reaction, and “+” to “+++” = positive reactions of increasing intensity (on a 5-graded scale, for which no reactions reached the two highest levels “++++” or “+++++”). Empty spaces represent negative reactions.
