HbF levels in patients with moderately elevated HbA1c and TNF-α.

Parameters	HbF level (%)	P value∗
HbA1c (%)
Upper 25th percentile (>7.6)	1.12 ± 0.84	0.741
Lower 25th percentile (<6.5)	1.06 ± 0.78
TNF-α (pg/mL)
Upper 25th percentile (>95.2)	1.28 ± 0.97	0.011
Lower 25th percentile (<10.3)	0.82 ± 0.53

Data are expressed as mean ± SD. ^∗The upper 25th percentile values were compared with the lower 25th percentile values for each parameter. HbA1c: glycated hemoglobin; TNF-α: tumor necrosis factor-α; HbF: fetal hemoglobin.
