Excluded studies
From the 32 full-text papers that we screened, we excluded 13
studies (see the
Characteristics of excluded studies
table). We ex-
cluded most of the studies (nine out of 13) because falls were col-
lected as a measure of an adverse event. These studies, theref
ore,
although reporting falls, did not have the aim of preventing
them.
We excluded
Barreca 2004
because the study was not truly ran-
domised,
Eng 2010
because it was a narrative review,
Halvarsson
2011
because the subgroup of people with stroke consisted of only
four participants, and
Mayo 1994
because the author was unable
to provide us with details and data for the stroke subgroup.
Our searching activities did not identify any ongoing trials.
We had insufficient information on four studies, and these awa
it
classification. Prior to publication of the review, we identifie
d one
additional potential study through contact with an expert: th
is
is also awaiting classification (see the
Characteristics of studies
awaiting classification
table).
Risk of bias in included studies
For five out of six items of our risk of bias assessment, the maj
ority
of our included studies scored as having low risk of bias. Only
for blinding of outcome assessment (detection bias) did we score
the majority of the included studies as having a high risk of bi
as.
Details of risk of bias assessment for each study are shown in
the
Characteristics of included studies
table. Summary results are
shown in
