Two studies investigated the effect of medication on falls; Sato 2005a compared vitaminDwith placebo and Sato 2011 compared alendronate with alphacalcidol. Haran 2010 examined the effect of single lens distance vision glasses instead of multifocal glasses,and this is classified in the ProFaNE taxonomy under Environment/ Assistive technology (aids for communication, information and signalling). Holmgren 2010 evaluated the effect of a multiple intervention that largely consisted of individualised and homebased exercises. Finally, Batchelor 2012 examined the effect of a multifactorial intervention that also partly consisted of an individualised home exercise programme but included a comprehensive risk assessment and referral for a wide range of risk factors.

included studies.
