Title
The distinction between randomized clinical trials (RCTs) and preliminary feasibility and pilot studies: what they are and are not.

Abstract

Feasibility and pilot studies play an important role in the preliminary planning of a proposed full-size randomized clinical trial (RCT). In essence, feasibility studies are used to help develop trial interventions or outcome measures, whereas pilot studies replicate, in miniature, a planned full-size RCT. However, the terms used for these preliminary studies are sometimes considered synonymous, and in practice may overlap considerably or be combined. The important issue is not the distinction between these: the important distinction is between such preliminary studies and a proper RCT.

Attention Score in Context

Attention Score in Context

This research output has an Altmetric Attention Score of 10. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 04 January 2023.
All research outputs
#4,997,052
of 34,365,356 outputs
Outputs from Journal of Orthopaedic & Sports Physical Therapy
#1,227
of 2,749 outputs
Outputs of similar age
#41,134
of 271,749 outputs
Outputs of similar age from Journal of Orthopaedic & Sports Physical Therapy
#17
of 36 outputs
Altmetric has tracked 34,365,356 research outputs across all sources so far. Compared to these this one has done well and is in the 85th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 2,749 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 26.7. This one has gotten more attention than average, scoring higher than 55% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 271,749 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 84% of its contemporaries.
We're also able to compare this research output to 36 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 52% of its contemporaries.
