evidence: Both peak blood glucose and the amplitude of glycemic excursion were lower after PX and SC than PC (P < 0.01 for each) and were lowest after SX (P < 0.05 for each), while overall blood glucose was lower after SX than PC (P < 0.05).
intervention: sitagliptin and d-xylose
comparator: placebo and sucralose
outcome: overall blood glucose
