But industry groups are slowly making progress with standardising valuation methodology.
All fish were sampled with standardised hook and line fishing gear.
With standardised registration forms, data were collected during a 6-month period.
Participants were provided with standardised off the shelf wedge insoles and permitted to wear them in their own shoes.
Even when acuity was measured with standardised charts by experienced eye care providers, there was no reliable difference in UVA in children with refractive error and those with unexplained reduced UVA which normalised over time.
The strengths of the study include the prospective population based design, the large number of participants with MRI data, over 10 years follow-up, and the high level of detailed reporting of risk factors measured with standardised methods.
For example, coregistration of biopsy against the processed specimen has numerous methodological problems that include orientation error, gland shrinkage and distortion, tissue loss through trimming, and difficulty with standardising distance measurements in the direction of the needle axis.
Randomised trials, in education could suffer due to difficulty with standardising the educational intervention(s), contamination between the two arms of a study, inability to blind the study participants and the teachers from the educational intervention(s) leading to selective co intervention, and finally difficulty with measuring outcomes due to the lack of valid and reliable assessment tools.
A meta-analysis published in 2005 that included three randomised trials with a total of 99 participants that reported sleep quality [11] a statistically non-significant improvement with valerian (standardised mean difference 1.38, 95% CI-0.49 to 3.25) with substantial heterogeneity among the trials (I2 = 90.3%).
The results revealed that usmad3 levels were independently correlated with eGFR (standardised β = 0.373; t = 3.527; p = 0.001) in patients with T2DM and an eGFR ≥90 ml/min/1.73 m, whereas they were also independently correlated with eGFR in patients with T2DM and an eGFR <90 ml/min/1.73 m (standardised β = −0.305; t = −2.696; p = 0.009).
