The result of Egger’s test for TNF-α was t = -4.59 (Figure 6A), and its absolute value was greater than 0.05, indicating that there was no publication bias. The result of the egger’s test for IL-1β was t= - 4.21(Figure 6B), and the absolute value of the t value was greater than 0.05, so it was considered that there was no publication bias.
