CD14 and adult-onset Still disease: The percentage of elevated LPO on CD14+ cells was significantly higher in active AOSD patients (median 97.96, IQR 90.0–99.5) than in HC subjects (median 87.3, IQR 60.1–87.5, p < 0.05), but no significant difference was observed between inactive AOSD patients (median 95.06, IQR 78.5–97.5) and HC subjects (Figure 1F).
