Theophylline 29-41 erythropoietin Homo sapiens 64-78 9625339-1 1998 UNLABELLED: Theophylline administration has been shown to attenuate erythropoietin (EP) production in adults; the effect of caffeine is not known. Theophylline 12-24 erythropoietin Homo sapiens 68-82 9625339-1 1998 UNLABELLED: Theophylline administration has been shown to attenuate erythropoietin (EP) production in adults; the effect of caffeine is not known. Theophylline 12-24 erythropoietin Homo sapiens 84-86 9625339-2 1998 Our aim was to determine whether caffeine and theophylline had similar effects on EP production in the premature newborn. Theophylline 46-58 erythropoietin Homo sapiens 82-84
