Table 2 Results of carotid artery ultrasounds and IL-33 and sST2 measurements

From: Methotrexate use, not interleukin 33, is associated with lower carotid intima-media thickness in patients with rheumatoid arthritis

Variable Value
IMT - CCA (mm - median (IQR)) 0.7 (0.6–0.8)
Increased IMT (n (%)) 19 (18.6)
Atherosclerotic plaque (n (%)) 24 (23.5)
IL-33 (pg/mL - median (IQR))a 32.1 (0–78.7)
IL-33 (pg/mL - median (IQR))b 69.1 (31.6–114.5)
sST2 (pg/mL - median (IQR))c 469.8 (336.3–651)
IL-33/sST2 (median (IQR))d 0.1 (0–0.3)
  1. IMTintima-media thickness, CCA common carotid artery; and IQR interquartile range. According to the manufacturer, the minimum detectable concentration of IL-33 and sST2 was 23.4 and 31.2 pg/ml, respectively
  2. alevels below the limit of detection were considered as zero
  3. bonly considering the 68 participants with levels above the limit of detection
  4. |conly considering the 101 participants with levels above the limit of detection
  5. dIL-33-to-sST2 ratio
