Randomized Controlled Trial Multicenter Study
MR CLEAN, a multicenter randomized clinical trial of endovascular treatment for acute ischemic stroke in the Netherlands: study protocol for a randomized controlled trial.
Endovascular or intra-arterial treatment (IAT) increases the likelihood of recanalization in patients with acute ischemic stroke caused by a proximal intracranial arterial occlusion. However, a beneficial effect of IAT on functional recovery in patients with acute ischemic stroke remains unproven. The aim of this study is to assess the effect of IAT on functional outcome in patients with acute ischemic stroke. Additionally, we aim to assess the safety of IAT, and the effect on recanalization of different mechanical treatment modalities. ⋯ If IAT leads to a 10% absolute reduction in poor outcome after stroke, careful implementation of the intervention could save approximately 1% of all new stroke cases from death or disability annually.

Randomized Controlled Trial Multicenter Study
Chinese medicine combined with calcipotriol betamethasone and calcipotriol ointment for Psoriasis vulgaris (CMCBCOP): study protocol for a randomized controlled trial.
Psoriasis causes worldwide concern because of its high-prevalence, as well as its harmful, and incurable characteristics. Topical therapy is a conventional treatment for psoriasis vulgaris. Chinese medicine (CM) has been commonly used in an integrative way for psoriasis patients for many years. Some CM therapies have shown therapeutic effects for psoriasis vulgaris (PV), including relieving symptoms and improving quality of life, and may reduce the relapse rate. However, explicit evidence has not yet been obtained. The purpose of the present trial is to examine the efficacy and safety of the YXBCM01 granule, a compound Chinese herbal medicine, with a combination of topical therapy for PV patients. ⋯ To address the effectual remission of the YXBCM01 granule for PV, this trial may provide a novel regimen for PV patients if the granule can decrease relapse rate without more adverse effects.

Randomized Controlled Trial Multicenter Study
Traditional Chinese medicine (Shun-Qi-Tong-Xie Granule) for irritable bowel syndrome: study protocol for a randomised controlled trial.
Irritable bowel syndrome (IBS) is a common gastrointestinal functional disorder with no effective therapy. Traditional Chinese medicine (TCM) is one of the most common complementary therapies in China. We designed this study to evaluate the efficacy and safety of Shun-Qi-Tong-Xie Granule (SQTX Granule), a TCM treatment, in patients with IBS with diarrhea (IBS-D). ⋯ According to TCM theory, SQTX Granule has a regulating effect on abdominal pain, diarrhea and the syndrome of liver-spleen disharmony, which is similar to the symptoms of IBS-D. This study will provide objective evidence to evaluate the efficiency and safety of SQTX Granule in IBS-D treatment.

Randomized Controlled Trial Multicenter Study Pragmatic Clinical Trial
Effectiveness and cost-effectiveness of telehealthcare for chronic obstructive pulmonary disease: study protocol for a cluster randomized controlled trial.
Several feasibility studies show promising results of telehealthcare on health outcomes and health-related quality of life for patients suffering from chronic obstructive pulmonary disease, and some of these studies show that telehealthcare may even lower healthcare costs. However, the only large-scale trial we have so far - the Whole System Demonstrator Project in England - has raised doubts about these results since it conclude that telehealthcare as a supplement to usual care is not likely to be cost-effective compared with usual care alone. ⋯ There has been a call for large-scale clinical trials with rigorous cost-effectiveness assessments in telehealthcare research. This study is meant to improve the international evidence base for the effectiveness and cost-effectiveness of telehealthcare to patients suffering from chronic obstructive pulmonary disease by implementing a large-scale pragmatic cluster-randomized clinical trial.

Randomized Controlled Trial Multicenter Study Comparative Study
Live birth after fresh embryo transfer vs elective embryo cryopreservation/frozen embryo transfer in women with polycystic ovary syndrome undergoing IVF (FreFro-PCOS): study protocol for a multicenter, prospective, randomized controlled clinical trial.
Polycystic ovary syndrome (PCOS) patients are at increased risk of pregnancy complications, which may impair pregnancy outcome. Transfer of fresh embryos after superovulation may lead to abnormal implantation and placentation and further increase risk for pregnancy loss and complications. Some preliminary data suggest that elective embryo cryopreservation followed by frozen-thawed embryo transfer into a hormonally primed endometrium could result in a higher clinical pregnancy rate than that achieved by fresh embryo transfer. ⋯ We hypothesize that elective embryo cryopreservation and frozen-thawed embryo transfer will reduce the incidence of pregnancy complications and increase the live birth rate in PCOS patients who need IVF to achieve pregnancy.
