Additional file 8 of Anti-Toxoplasma gondii efficacy of beta, beta-dimethylacrylshikonin and isobutyrylshikonin in vitro and in vivo

Additional file 8: Figure S6. Confirmation for the OPLS-DA score plots in ESI+ (A & B) and ESI- (C &D). (A & C) DMAS vs control (pR2Y = 0.025, pQ2 = 0.01 ESI+; pR2Y = 0.02, pQ2 = 0.02 ESI-); (B & D) IBS vs control (pR2Y = 0.005, pQ2 = 0.005 ESI+; pR2Y = 0.005, pQ2 = 0.005 ESI-). The blue and red horizontal lines indicate R2 and Q2 in original model, and their values post permutation are marked with corresponding color diamond points, respectively. The points on or under the horizontal line, that is, the values post permutation no more than that in original model, suggest the employed model is efficient and useful.
