Figure 1. Changes over time and relationship between the number of S. mutans and proteinuria.
Change in the number of S. mutans over time (a). Change in proteinuria over time (b). p < 0.05 was considered statistically significant in the Friedman test, and p < 0.0167 was considered statistically significant in the Bonferroni correction (*).
S. mutans: Streptococcus mutans.

Figure 2. Relationship between reaching S. mutans <10³ CFU/mL and achieving proteinuria <0.3 g/gCr after 12 months in patients with IgA nephropathy or chronic glomerulonephritis.
(a) Rate of proteinuria <0.3 g/gCr at month 0 in patients with IgA nephropathy or chronic glomerulonephritis. (b) Rate of proteinuria <0.3 g/gCr after 12 months in patients with IgA nephropathy or chronic glomerulonephritis. p < 0.0167 was considered statistically significant in the Bonferroni correction (*).
CFU: colony-forming unit; S. mutans: Streptococcus mutans.

Figure 3. Number of Streptococcus mutans in saliva.
The number of S. mutans in saliva from each patient at month 0.

Figure 4. Grouping chart.
Patients were divided into three groups: <10³ colony-forming units (CFU)/mL S. mutans at month 0, and those with < and ≥10³ CFU/mL S. mutans after 12 months.
