Dataset from Complementary and Alternative Medicine for Urological Symptoms (CAMUS)

The CAMUS trial will test Saw palmetto in about 369 men. Men who decide to be part of the
CAMUS trial will be given one out of two possible treatments at random. One out of every two
men would get an inactive placebo treatment. One out of every two men would get Saw palmetto
pills.

This kind of scientific study is the best way to find out if the plant extracts really work
to prevent men with benign prostatic hyperplasia (BPH) from getting worse. During the study,
men will not know which of the two treatments they are assigned to. They will be followed
very closely by a study team every 12 weeks to see how they are doing. Men in the CAMUS trial
will be studied over 72 weeks. Tests and all medications needed as part of the study will be
provided at no charge to the participant. Participants will be responsible for all other
costs not associated with the study tests and medications. All information on study
participants will be held in the strictest confidence and no one would have access to patient
information other than the required authorized health care and research personnel.

CAMUS试验将招募约369名男性受试者，对锯叶棕（Saw palmetto）的疗效进行评估。有意参与本试验的男性将通过随机方式被分配至两种干预方案之一：每两名受试者中即有一人接受无活性安慰剂治疗，另一人则服用锯叶棕片剂。

此类科学研究是验证植物提取物能否有效阻止良性前列腺增生（benign prostatic hyperplasia, BPH）患者病情恶化的最优研究方案。本试验中，受试者无法知晓自身被分配至哪一种治疗方案。研究团队将每12周对受试者进行一次密切随访，评估其健康状况。整个试验周期为72周。试验所需的各项检测及研究用药均免费向受试者提供，受试者仅需自行承担与研究检测、用药无关的其他费用。所有受试者的研究相关信息将被严格保密，仅经授权的医疗保健与研究人员可接触患者个人信息。
