Definition: Given an abstract, indicate which of the provided candidate titles (Option1 and Option2) best describes it (respond with the text of the title, not option1/2).
Input: Abstract: Skin reflectance values were used as an objective measure of skin haemoglobin content at patch test sites to facilitate quantification of the erythematous response to contact allergens in patients with allergic contact dermatitis. Reflectance measurements of patch test responses correlated well with the clinical scoring and provided a numerical measure of reaction severity. Experimental contact allergen formulations were also evaluated by this method.
Which is the apt title for the abstract? option1: Skin reflectance measurements of patch test responses. option2: An appraisal of plastic reconstruction of the external nose.
Output:
Skin reflectance measurements of patch test responses.
