Table 2. CVM sample group categorization and biochemical properties.

Group	Nugent score	D-Lactic acid (% w/v)	L-Lactic acid (%w/v)	pH
1	0–3	0.68 ± 0.23 (high)	0.46 ± 0.13	3.81 ± 0.21
2	0–3	0.20 ± 0.11 (low)	0.65 ± 0.29	4.22 ± 0.65
3	4–6	0.11 ± 0.13	0.24 ± 0.20	5.06 ± 0.41
4	7–10	0.12 ± 0.15	0.22 ± 0.15	5.08 ± 0.48

Group assignments based on Nugent score, D- and L-lactic acid content and pH. pH and lactic acid values are reported as mean ± SD.
