About this example
Many published reviews, and reviews updated from RevMan 5, still use the original Cochrane tool with seven domains and low, unclear or high risk. Its tables are often written with symbols, and here they are pasted as they are: + for low, ? for unclear and − for high risk.
Without an Overall column the plot shows the domains only, which matches how RoB 1 was usually reported. For new reviews of randomised trials, Cochrane recommends RoB 2.
