Comparison of SFR, 12 + log(O/H), M_H2, and M_HI in segregated M_star bins for the MAGMA sample. The gray regions correspond to the standard deviations (±1σ), and the horizontal dashed line represents the zero difference (by definition) relative to the sample median. The nine different parent samples comprising MAGMA are shown by different symbols given in the legend in the upper right corner. The points and their error bars correspond to the median of the difference, relative to the median parameter of the MAGMA sample as a whole.
