Dot plot for peptide with sequence ALPAPIEJ in the GCM study. The vertical axis indicates abundance on the log2 scale. The horizontal axis indicates study group. Numbers in the plot indicate the MS experiment in which the peptide was detected. The circles with + inside to the right of the points for a given study group indicate the mean for that study group. While this peptide has a small p-value, it appears that observations in run 6 are driving the significance. Relying on p-value alone isn't enough; one needs to look at data for a complete interpretation.
