Intragroup analyses of clinical parameters at posttherapy examination. In the non-JP2-strain-infected group, clinical parameters, including PD, CAL, and GI, were compared between the subgroup of subjects who retained a detectable colonization by non-JP2 strains [non-JP2(+); n = 18] and the subgroup of subjects who lost detectable colonization by non-JP2 strains [non-JP2(−); n = 7], as measured at posttreatment examination (12 months). The same intragroup analyses for PD, CAL, and GI were carried out for the JP2-strain-infected group by comparison between JP2(+) subjects (n = 14) and JP2(−) subjects (n = 11) at posttreatment examination. The columns and bars indicate averages and standard errors, respectively. *, either the value for the JP2(+) subgroup or the value for the JP2(−) subgroup is significantly higher than that for any subgroup in the non-JP2-strain-infected group (Mann-Whitney test); **, significantly higher than non-JP2(+), non-JP2(−), or JP2(−) subgroups, by Mann-Whitney test; #, no statistical difference by ANOVA and Student's t tests.
