For all three symptoms, the effects of age and, for hip pain, sex were unchanged in secondary analyses that adjusted for variations between practices in their overall likelihood of referral (see web extra).
Generalized linear Poisson models and distributed lag nonlinear models (DLNM) were adopted to estimate the effects of temperature, relative humidity, temperature fluctuation, duration of sunshine, and rainfall on malaria transmission while adjusting for seasonal variation, between-year variation, and other climatic factors.
Linear regression used random effects to adjust for between-patient variations.
The mixture was prepared to adjust for potential variations between individual samples.
Power of Model A decreased dramatically as ICC departed from 0, indicating that the model failed to adjust for between-centre variation or within-centre correlation in the outcome measure.
Therefore, the relative effect of zinc on the common cold duration was calculated in percentages, because the relative effect adjusts for variations between the patient groups and outcome definitions.
(These figures aren't adjusted for price variations between regions).
The levels of PTK6 transcripts were normalized against the levels of cyclophilin mRNA which was used as an internal control, and for comparison of different exons, starting quantities were also normalized to a PTK6 plasmid control to adjust for variations in primer efficiencies between different exons.
First, we employed the average in-hospital mortality rate as an additional output to adjust for variations in the quality of care between hospitals [ 41].
To do so, we used the average in-hospital mortality rate per year for each hospital to adjust for variations in the quality of care between hospitals.
† adjusted for between-household variation and between-cluster variation as appropriate and a priori for latrine access, time to water and district.
