Table 1. Criteria for the Risk of Bias Assessment
Criteria
Operationalization
A. Was the method of randomization adequate? A. A random (unpredictable) assignment sequence. Examples of
adequate methods are computer generated random number table
and use of sealed opaque envelopes. Methods of allocation using
date of birth, date of admission, hospital numbers, or alternation
should not be regarded as appropriate
B. Was the treatment allocation concealed? B. Assignment generated by an independent person not responsible
for determining the eligibility of the patients. This person has
no information about the persons included in the trial and has no
influence on the assignment sequence or on the decision about
eligibility of the patient
C. Were the groups similar at baseline regarding the most important
prognostic indicators?
C. In order to receive a “yes,” groups have to be similar at baseline
regarding demographic factors, duration and severity of complaints,
percentage of patients with neurologic symptoms, and
value of main outcome measure(s)
D. Was the patient blinded to the intervention? D. The reviewer determines if enough information about the
blinding is given in order to score a “yes.”
E. Was the care provider blinded to the intervention? E. The reviewer determines if enough information about the
blinding is given in order to score a “yes.”
