| 3 June 2014 | New citation required but conclusions have not changed | This review is an update of the previous Cochrane systematic review (Rose 2013). We found and included six new trials. In general our review reaches the same conclusions as our previous review that included 15 trials. However, we included more trials and thus have more precise estimates for the effects of automated systems on our primary and secondary outcomes. |
