FGF19 and allergic asthma: The proteins FGF19, interleukin 2 (IL‐2), IL‐4, and monocyte chemotactic protein 3 (MCP3) were associated with allergic asthma, whereas IL‐5, interleukin 6 (IL‐6), silent information regulator‐2‐like protein 2 (SIRT2), signalling lymphocytic activation molecule (SLAMF1), STAM‐binding protein (STAMBP), and uPA associated with non‐allergic asthma in the model adjusted for sex, BMI and body fat percentage (Table 4, Figure 2).
