CD68 and cervical cancer: The results showed that there were no statistical significance [WMD = -4.63, 95% CI: (-17.21, 7.95), P=0.47]; [OR = 0.33, 95% CI: (0.05–2.21), P=0.26], indicating that there was no significant difference in the correlation between CD68+ TAMs and different histological grades of cervical cancer (Figure 6B,C).
