From: Frailty is related to serum inflammageing markers: results from the VITAL study
Principal component analysis (PCA) comparing the inflammageing markers in participants over 60 years of age between different classes of scores on the Frailty Index. The log-transformed markers were included in the PCA analysis. Participants (n = 187) were divided into different frailty classes; the red dots represent the participants with the lowest frailty scores and the blue and purple dots the participants with the highest frailty scores. The percentage of variance explained by the Principle Components (PC) 1 and 2 are mentioned on the axis. The eclipses cover 80% of the datapoints
