In this review, 48.3% of the selected studies only evaluated PRP treatment's efficacy with a few questionnaire-reported or subjective measures, as opposed to the ideal multifaceted evaluation; therefore, they were classified as having poor outcome measures.
Only a few questionnaires had missing data.
A few questionnaires were administered by telephone.
A few questionnaires with missing information on key variables were also excluded.
There are only a few questionnaires for organizational culture which are clinic-specific (e.g. Hospital Culture Questionnaire [ 43], The Hospital Culture Scale [ 44]), or used in a clinical setting [ 45].
By contrast, a few questionnaires such as the Social Responsiveness Scale-Adult version (SRS-A) [ 15], or the Autism Spectrum Disorder in Adults Screening Questionnaire [ 16] must be completed by another adult (e.g., family member, close friend, or professional).
In addition, we were concerned that the mean site level barrier score might be a biased estimate of the true site average if only a few questionnaires were completed at a site, therefore we conducted a sensitivity analysis by running models excluding ICUs with less than 10 completed barrier questionnaires.
The quality of the allocations depends on the desired number of sequences/batch sizes, since the FCM built from a few questionnaires may not be as representative of the underlying dynamics as if it was synthesizing the knowledge of all participants.
A few electronic questionnaire development tools were available, such as the Microsoft.NET Compact Framework, Census and Survey Processing System (CSPro), 24 Visual CE, etc.
There are a few validated questionnaires such as the ID migraine to diagnose migraine, and the migraine disability assessment score (MIDAS) to assess disability in the last 3 months, but there is no comprehensive questionnaire to assess migraine associated burden.
