2. Figure 1
Intraclass correlation coefficients (ICCs) for agreement and consistency for the two rounds of photographic testing (stage 1, rounds 1 and 2). For both rounds of testing, the ratings were significantly correlated for scale (ICCs near 0.7 or greater). The interrater reliability for erythema was lower (ICCs less than 0.7).

Intraclass correlation coefficients (ICCs) for agreement and consistency for the three rooms during in-person evaluations at the Foundation for Ichthyosis and Related Skin Types conference (stage 2). For all rooms, the ratings were found to be highly correlated for scale and erythema (ICCs near 0.7 or greater).

4. Figure 3
Intraclass correlation coefficients (ICCs) for agreement and consistency for the combined scores for scale and erythema, as well as the final total scores during in-person evaluations at the Foundation for Ichthyosis and Related Skin Types conference (stage 2). For all rooms, the ratings were found to be highly correlated for scale and erythema (ICCs greater than 0.7).
