TASK: Your task is to answer biomedical questions using the given abstract. Only output yes, no, or maybe as answer.
INPUT: ['To compare the efficacy of three commercially available oral lactase preparations in adults with lactose intolerance.', 'Design--Prospective, randomized, placebo-controlled trial. Setting--Outpatient study in a General Clinical Research Center. Subjects--Ten lactose-intolerant healthy volunteers were challenged with ice cream containing 18 g of lactose. Lactase or placebo was given immediately prior to challenge. Measurements--Symptoms and breath hydrogen excretion were recorded for 3 h following lactose challenge.', 'The three products differed in their abilities to influence symptoms and breath hydrogen excretion. Only Lactaid reduced the breath hydrogen excretion with lactose (mean peak, area under the curve and cumulative breath hydrogen excretion) (p < 0.05). Lactrase and Dairy Ease influenced symptoms: Lactrase reduced pain, bloating and total symptomatic scores (p < 0.05), whereas Dairy Ease only reduced pain (p < 0.05). Lactaid administration did not reduce symptoms.'] Are all lactase preparations the same : results of a prospective , randomized , placebo-controlled trial?
OUTPUT:
