PEBP1 and asthma: Figure 2A–C compare individuals with and without asthma, showing significantly reduced PEBP1 (pg/mL), elevated 15-LO-1 (pg/mL) and 15-LO-1/PEBP1 ratio levels in the asthma group. Figure 2D–F further stratify the data by asthma severity (moderate, severe, and healthy controls), revealing a decrease in PEBP1 (pg/mL), and increase in 15-LO-1 (pg/mL) and 15-LO-1/PEBP1 ratio levels.
