Table 2 Mean tumor burden per rat and tumor burden per group

From: Modulation of N-methyl-N-nitrosourea induced mammary tumors in Sprague–Dawley rats by combination of lysine, proline, arginine, ascorbic acid and green tea extract

Rat group

Total tumor burden per group

Mean tumor burden per rat

Control group (n = 10; 19 tumors)

183.2 cm2

18.3 ± 1.3 cm2

Supplemented group (n = 10; six tumors)

72.2 cm2

7.22 ± 1.8 cm2

  1. The mean tumor burden per rat is expressed as mean ± standard deviation. The differences between groups were significant (P < 0.0001).
