RS compared with RRS intensities for 52 women over 12 time points. Colored lines represent the slope for each person over the year. Per maximum likelihood, the overall between-person correlation between the two skin carotenoid scores was 0.76 (P < 0.001) and the overall within-person correlation coefficient was 0.30 (P < 0.03). RS, reflection spectroscopy; RRS, resonance Raman spectroscopy
