With a highly significant F value of 1,009.134 and P value <0.001 for the 5 μM concentration, the mean percentage viability of H1299 cells ( Table 7 ) decreases from 72.25% (±2.39) at 5 μM to 48.84% (±1.17) at 30 μM and 27.63% (±0.59) at 50 μM EGCG, confirming the repeatability of this dose-dependent response.
