Figure 3.

Agreement between PQN coefficients estimated from the standard ¹H NMR spectra and the corresponding SMolESY processed data. The linear regression trendline (dashed red line) was estimated with the orthogonal least-squares Passing–Bablok method. The regression coefficients, Pearson correlation coefficient (ρ) and the p-value from the two-sided correlation significance test are shown in the top left corner. Data points are colored by the natural logarithm of the estimated protein concentration (mg/mL).
