These guidelines were based on two very small methodologically flawed randomised controlled trials (RCTs).
Both of these studies had design flaws, including very small sample sizes [ 16] and high dropout rates [ 12], limiting conclusions.
Nevertheless, they concluded the acupuncture intervention as "unknown effectiveness" in their report, due to the fact that the analyzed studies were of very small sample size and had flaws in the study design, including uncertain allocation concealment, substantial loss to follow up and lack of assessments for potential adverse effects.
In a comparison of acupressure with oxybutinin for nocturnal enuresis in children[ 91], the main flaw was the very small sample size, with no details of sampling, comparison of groups or randomisation, potential selection bias and no placebo/sham group.
While constructing libraries from these very small samples, we encountered a significant flaw in the TS-PCR method as originally described [ 12]: a substantial quantity of cDNA spanning a size range that might be expected to represent a typical biological sample is synthesized in the absence of any starting RNA.
At very high strain rates, however, crack growth is activated even in small flaws and therefore controlling the total number density rather than the size of the flaws is effective for increasing dynamic strength.
Cracks are very small voids in the internal microscopic crystalline structure of the material, and form small discontinuities (flaws) inside the material.
Mr. Sansonetti said in an interview that Mr. Rove had told him the Bush campaign thought the plan was flawed because candidates would have to undergo heavy, tiring travel in February, when a dozen very small states would vote.
"Uyuni was very, very small.
