Frequency of categories of specific metric (element 3) and method of aggregation (element 4) across instances of usage of outcome domains by condition.

Notes:• If there was no instance of usage of a certain outcome domain across all reviews addressing a given condition, the above table does not include a row for that outcome domain for that condition.• Percentages are row percentages (adding up individual categories within an element). Percentages sometimes total more than 100% for an element because some protocols used more than one category for that element.• No reviews used “median” as a method of aggregation (element 4).Frequency of categories of specific metric (element 3) and method of aggregation (element 4) across instances of usage of outcome domains by condition.
