Fig. 10. Peak force produced during contraction cycles at 37 Hz in relation to the sum of the relative abundance of troponin T (TnT) transcripts 261 and 267. Symbols are as in Fig. 6. The point at the far left of the plot was excluded from the statistical analysis and the curve fit because it does not conform to either linear or curvilinear models. It does, however, support the association between low levels of particular TnT transcripts and force output.
