Kaplan-Meier plot of equivalent cycles for current lightweight folding wheelchairs study (LWFW II) and four previous studies: lightweight folding wheelchairs I (LWFW I) , aluminum ultra-light folding wheelchairs (AUFW) , titanium ultralight rigid wheelchairs (TURW) , and aluminum ultralight rigid wheel-chairs (AURW) . Note: Labels and leader lines show cumu-lative survival for each study at American National Standards Institute/Rehabilitation Engineering Society of North America (ANSI/RESNA) minimum equivalent cycles value.
