The differences in <i>Rickettsia</i> infection rates and mean altitude in <i>I</i>. <i>ovatus</i> haplotype groups and cluster dendrogram groups.

The table shows the distribution of Rickettsia-infected and uninfected I. ovatus and the mean altitude in each of the haplotype groups as shown in Fig 1 (I. ovatus haplotype network) and the cluster dendrogram in Fig 4 (I. ovatus cluster dendrogram). The z-score test showed a significant difference at p < 0.05 between the Rickettsia detection rates in haplotype groups 1 and 2 (indicated by ab) and in cluster dendrogram groups 1 and 2. The Welch t-test at p < 0.05 revealed a significant difference in the mean altitude of haplotype groups 1 and 3 and cluster dendrogram groups 1 and 2 indicated by ab. Haplotype group 4 was not included in the analysis due to its low sample size.
