Summary table for the nonadipose H&E images and corresponding spectra. The data are separated to show the number of data points above and below the median % collagen. The summary shows the number of sites, MBD, age, menopausal status, and tissue type. Sites with a high percentage of collagen were mostly from MBD of 2 or higher. FG sites had at least 56% or higher collagen.
