Development of a Physiological Frailty Index for the World Trade Center General Responder Cohort

Figure 1

Plots depicting the rate of abnormal values of physiological parameters over ages 40–70. Each plot corresponds to one physiological parameter, with black dots representing raw data (% of individuals of a certain age with abnormal values on a physiological parameter). Smooth fits (solid red curve) were computed using locally weighted scatterplot smoothing (LOESS). Spearman correlation is provided on the top left corner of each plot. BUN: blood urea nitrogen; MCV: mean corpuscular volume; MCH: mean corpuscular hemoglobin; RDW: red cell distribution width; WBC: white blood cell; NLR: neutrophil-to-lymphocyte ratio.
