CXCL8 and diabetes mellitus: Among those with diabetes over the study period (total n = 138), significant positive associations were observed with nearly all exposure windows for IL-1β and with later daily lags for IL-6, IL-8, and TNF-α [e.g., IL-6 increased 55.1% at lag 3 (95% CI: 16.7, 106.3; interaction p-value < 0.01), and IL-8 increased 19.9% at lag 4 (95% CI: 5.3, 36.4; interaction p-value < 0.01), and TNF-α increased 17.7% at lag 3 (95% CI: 0.3, 38.1; interaction p-value = 0.14)].
