Table 2.
Comparison of dual-energy computed tomography (DECT) volumes of monosodium urate deposition, number of joints presenting with the double contour (DC) sign, and serum urate levels depending on whether the metabolic syndrome is present or not
| Total population (n = 42) |
No metabolic syndrome (n = 14) |
Metabolic syndrome (n = 28) |
p value | |
|---|---|---|---|---|
| Number of joints with DC sign | 2 (2–3) | 2 (1–3) | 2 (2–3) | 0.65 |
| DECT volume knees (mm3) | 0.2 (0–1) | 0.4 (0–0.6) | 0.1 (0–1.2) | 0.91 |
| DECT volume feet (mm3) | 0.5 (0.1–1.8) | 0.8 (0.3–1.9) | 0.4 (0–1.3) | 0.46 |
| DECT volume knees + feet (mm3) | 0.8 (0.2–2.8) | 1.2 (0.6–2.2) | 0.4 (0.1–2.3) | 0.29 |
| Serum urate level (mg/dL) | 7.6 (6.8–9.4) | 7.6 (7.2–8.8) | 7.5 (6.0–9.4) | 0.63 |
As the Mann-Whitney-Wilcoxon test was used (no normality), data are expressed as median (interquartile range)
