  • a Higher values indicate better reproducibility. Six replicate fingerprints per strain were included in each analysis.

  • b With A separate from B, for standard versus 65-TD cycling, P = 0.02 (ERIC2 and BOXA1R) and P = 0.06 (composite).

  • c With A and B combined, for standard versus 65-TD cycling, P < 0.001 for all comparisons.

  • d With standard cycling, for A separate from B versus A and B combined, P < 0.001 for all comparisons.

  • e With 65-TD cycling, for A separate from B versus A and B combined, P > 0.10 (ERIC2 and composite) and P = 0.01 (BOXA1R).
