Randomized Controlled Trial
Randomized clinical trial of the use of glyceryl trinitrate patches to aid arteriovenous fistula maturation.
Arteriovenous fistulas are critical for haemodialysis, but maturation rates remain poor. Experimental and anecdotal evidence has supported the use of transdermal glyceryl trinitrate (GTN) patches. The aim of this RCT was to determine whether use of a GTN patch aids arteriovenous fistula maturation. ⋯ NCT01685710 (http://www.clinicaltrials.gov).

Randomized Controlled Trial Multicenter Study Comparative Study
Randomized clinical trial of single-incision versus multiport laparoscopic colectomy.
The efficacy and safety of single-incision laparoscopic colectomy (SILC) for colonic cancer remain unclear. The aim of this study was to determine the outcomes of SILC compared with multiport laparoscopic colectomy (MPLC) for colonic cancer. ⋯ UMIN000007220 (http://www.umin.ac.jp/ctr/index.htm).

Randomized Controlled Trial Multicenter Study
Five-year outcomes following a randomized trial of femorofemoral and femoropopliteal bypass grafting with heparin-bonded or standard polytetrafluoroethylene grafts.
Cohort studies suggest superior long-term patency of luminal heparin-bonded polytetrafluoroethylene (Hb-PTFE) bypass grafts compared with standard PTFE grafts. The aim of this study was to compare the outcomes of Hb-PTFE grafts with those of standard PTFE grafts 5 years after a randomized trial. ⋯ In this study there was no difference in primary graft patency between Hb-PTFE and standard PTFE grafts. Patients receiving Hb-PTFE grafts for critical limb ischaemia were more likely to have a patent graft at 5 years than those with standard PTFE grafts.

Randomized Controlled Trial
Two-year results from a randomized clinical trial of revascularization in patients with intermittent claudication.
Intermittent claudication is associated with significant impairment of health-related quality of life. The use of revascularization techniques to improve health-related quality of life remains controversial. ⋯ NCT01219842 (http://www.clinicaltrials.gov).
