Moreover, the meta-analysis results showed that patients with severe malaria had a higher SMD of the IL-10 level than those with non-severe malaria in the studies performed in Asia (p = 0.02, pooled SMD: 1.20, 95% CI: 0.17–2.24, I2: 95.93%, five studies/seven sub-studies, Figure 4). Here, IL10 is linked to malaria.
