LOS = length of stay; OMT = osteopathic manipulative treatment; R.C. = reference category. DRG-388 = diagnosis related groups, prematurity without major complications; DRG-387 = diagnosis related groups, prematurity with major complications; DRG-386 = diagnosis related groups, prematurity with respiratory distress syndrome.
