Data from 1H-NMR spectra of human meibum. Gray bars: azythromycin study. Filled bars: data are from a larger published study (labled MGD and Normal).12,13 Open bars: doxycycline study(labled DCN). A) The resonance at 5.2 ppm has been tentatively assigned to terpenoids.12,13 B) The resonance at 5.4 is assigned to unconjugated =CH protons. C) The resonance at 1.26 ppm has been tentatively assigned to short chain CH3 moieties.12,13 *Statistically significant difference, p < 0.05.
