Elemental abundances with respect to hydrogen ([X/H]) including metallicity and 11 elements determined from IGRINS spectra versus those in the APOGEE DR17 catalog for stars in common between APOGEE and this work. The black open circles and black open diamonds represent stars chemically classified as thin- and thick-disks, respectively, in our sample. The number of stars with valid APOGEE abundance estimates for each element are listed within the brackets in each panel. The linear one-to-one relation is shown by the black dashed line, and the mean difference values in metallicity and elemental abundances between this work and APOGEE are listed in the top-right part of each panel.
