Conditional logistic regression to adjust for the matching of case subjects and control subjects was used to determine the independent effect of the principal components and the composite score on the progression of CAC.
This condition should hold in most circumstances, and therefore the paired crossover design deserves serious consideration for any clinical trial in which the crossing over and matching of subjects is deemed simultaneously beneficial.
The main reason why we took sex, age and SLD into account is that the Dionysos Nutrition and Liver Study is a cross-sectional study with matching of subjects performed on the basis of SLD, age and sex [ 11].
The matching of subjects in the study was the closest that was possible on available demographic and health related criteria in an attempt to establish equivalence between the intervention and comparison group.
This analysis used propensity score matching of subjects from randomized placebo-controlled schizophrenia studies to compare paliperidone ER 6-12 mg/day with risperidone 2-4 mg/dandand risperidone 4-6 mg/day.
*** Via reference, ~in chart form Note: The reviewers recorded that matching of subjects and controls took place when this was stated by the authors and accompanied by supporting demographic details in the text.
Matching of subjects and controls was not documented or did not take place [ 12, 13, 17] or details incomplete [ 20] in four studies and may have accounted for differences between groups.
Because the Dionysos Nutrition and Liver Study is a cross-sectional study with matching of subjects performed on the basis of SLD, sex and age [ 11], we tested whether the addition of these variables had any effect on the ability of lnLAP to identify liver steatosis.
Based on 6 key criteria (matching of subjects and controls, power calculation justifying sample size, reproducibility of electrode position - this could include a reference for further details, reliability of EMG equipment, tester blind to group allocation, and sufficient results in the text or supplied by the authors) a maximum score of 6 was awarded to each study.
There's a wonderful match of subject and style here.
