Effect modification by ferritin levels on the relationship between high sensitivity C reactive protein and pulse wave velocity (PWV). Given the fact that an effect modification by ferritin exists (see Table 3), the estimated increase in PWV associated to 1 mg/l increase in hs-CRP must be calculated at predefined values of the effect modifier. Thus, in crude terms, when ferritin is 36 ng/ml (the 25th percentile), 86 ng/ml (the 50th percentile) and 159 ng/ml (the 75th percentile), the estimated increase in PWV associated to 1 mg/l increase in hs-CRP is 0.18 m/s, 0.26 m/s and 0.37 m/s, respectively. These three effects associated to a fixed increase in CRP (1 mg/l) statistically differ with a p value of 0.01. Data are crude and adjusted (Table 3—Model with effect modification) estimates. See “Methods”—“Statistical analysis” for more details
