Note: SIB = self-injurious behavior.

a

Of the 130 studies that reported protections, 32 did not provide sufficient information to determine the topography for any participant. Thus, data on topography were extracted from 98 of these studies.

b

Of the 130 studies that reported protections, 10 did not provide sufficient information to determine the function for any participant. Thus, data on function were extracted from 120 of these studies.

c

Of the 57 studies that did not report protections, eight did not provide sufficient information to determine the topography for any participant. Thus, data on topography were extracted from 49 of these studies.

d

Of the 57 studies that did not report protections, three did not provide sufficient information to determine the function for any participant. Thus, data on function were extracted from 54 of these studies.
