3.2.6 Publication bias
The results of the publication bias detection based on the main
indicators of the meta-analysis are as follows. 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.
