Levels of long-chain fatty acids in the patients with sarcoidosis and healthy controls. A–E Levels of n-3 poly-unsaturated fatty acids (PUFAs) (A), n-6 PUFAs (B), n-3/n-6 ratio (C), saturated fatty acids (SFAs) (D), and mono-unsaturated fatty acids (MUFAs) (E). The levels of serum fatty acids were measured by gas chromatography. The Mann–Whitney U-test was used to compare the levels of fatty acids. Gray, light gray, dark gray, and white data indicate all patients with sarcoidosis, patients with sarcoidosis and single organ involvement, patients with sarcoidosis and multiple organ involvement, and healthy controls, respectively. Horizontal lines, boxes, and error bars, represent the median, the 25th and 75th percentiles, and the 10th and 90th percentiles, respectively
