Model 1 had a more accurate quantification of the covariate effects for the spike-in compounds as well as for the unchanged non-annotated compounds in the benchmark experiment. Root-mean-square error (RMSE; y-axis) between the inferred and true covariate effects is smaller for Model 1 (All peaks) than for the single-peak approach (Single peak) at all the magnitudes of the true effect (x-axis). Differences were statistically significant for changes of 0 to 40% (Additional file 1: Table S3).
