研究衡量的是什么?

主要结果指标

结果测量
措施说明
大体时间
diffuse reflectance spectroscopy
大体时间:Baseline- immediately after irradiation to assess immediate pigment darkening
Diffuse reflectance spectroscopy is a non-invasive objective measure of pigmentation based on reflectance patterns of the irradiated skin
Baseline- immediately after irradiation to assess immediate pigment darkening
photography
大体时间:Baseline-immediately after irradiation to assess immediate pigment darkening
Cross polarized photography is used to document pigmentation non-invasively and reduce surface glare of the skin.
Baseline-immediately after irradiation to assess immediate pigment darkening
investigator's global assessment score
大体时间:Baseline- Immediately after irradiation to assess immediate pigment darkening
The investigator's global assessment score is a non-invasive subjective measure of pigmentation in which investigators assign a value ranging between 0, corresponding with no hyperpigmentation, to 5, or severe or dark hyperpigmentation.
Baseline- Immediately after irradiation to assess immediate pigment darkening
Diffuse reflectance spectroscopy
大体时间:24 hours after irradiation to assess persistent pigment darkening
Diffuse reflectance spectroscopy is a non-invasive objective measure of pigmentation based on reflectance patterns of the irradiated skin
24 hours after irradiation to assess persistent pigment darkening
photography
大体时间:24 hours after irradiation to assess persistent pigment darkening
Cross polarized photography is used to document pigmentation non-invasively and reduce surface glare of the skin.
24 hours after irradiation to assess persistent pigment darkening
Investigator's global assessment score
大体时间:24 hours after irradiation to assess persistent pigment darkening
The investigator's global assessment score is a non-invasive subjective measure of pigmentation in which investigators assign a value ranging between 0, corresponding with no hyperpigmentation, to 5, or severe or dark hyperpigmentation.
24 hours after irradiation to assess persistent pigment darkening
Diffuse reflectance spectroscopy
大体时间:7 days after irradiation to assess delayed tanning
Diffuse reflectance spectroscopy is a non-invasive objective measure of pigmentation based on reflectance patterns of the irradiated skin
7 days after irradiation to assess delayed tanning
Photography
大体时间:7 days after irradiation to assess delayed tanning
