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).
