TABLE 4.
Correlation between total antibody titers (including control and disease groups) to individual domains of RgpA and disease indices, including Dx score, mean probe depth of the periodontal pocket, and mean gingival AL around the teeth
Disease index | Titer correlation (rSp value)a

|||||
---|---|---|---|---|---|---|
LPS | rPAD | rHA1 | rHA2b | rHA3 | rHA4 | |
Dx score | 0.546* | 0.454† | 0.455† | Low | 0.524† | 0.432** |
Probing depth | 0.450† | 0.466† | 0.454† | Low | 0.516† | 0.443† |
AL | 0.485† | 0.525† | 0.509† | Low | 0.550* | 0.454† |
The correlation coefficient (rSp) was calculated by using Spearman's nonparametric, two-tailed analysis with 95% confidence intervals. Significance (determined by using Spearman's correlation) is indicated as follows: *, P < 0.05; †, P < 0.01; and **, P < 0.001.
Titers to rHA2 were not detected under the same ELISA conditions as for the other domains.
