Detailed quality assessment criteria would include modelling details such as allowance for multi-arm trials, specification of variance structures, and assessment of consistency of indirect evidence using different common interventions (that is, different loops of evidence in a treatment network).
The same trial sequential analysis specifications were used to model the potential effect of uncompleted registered studies.
Trial design, protocol specification, training, and continuous supervision led to a high degree of treatment fidelity for the counseling interventions in this randomized clinical trial and will increase confidence in the interpretation of the trial findings.
Although the test used in assessing the survival probabilities is nonparametric, the choice of a particular design during the planning stage of a trial depends on specification of the survival distribution as well as the accrual rate.
We run OLS specifications.
All beginners are accepted on a trial basis," the brochure specifications say.
A funded project in computational materials ("Materials Grid") http://www.materialsgrid.org/ which resulted in considerable development of CML specifications and trial implementations in a number of codes (CASTEP, DLPOLY).
We anticipated that 230 patients would have to be recruited to the trial to meet these specifications.
Explaining heterogeneity via the pre-specification of trial subgroups, graphical diagnostic tools and sensitivity analyses produced a more desirable outcome than an automatic application of the random effects model.
Therefore, while we acknowledge this is not a complete dataset, we believe selection bias in this study is minimised by the strict pre-specification of trial eligibility criteria including those related to trial size, quality, randomisation process, outcome definition, treatment comparison, and analysis as specified the published study protocol.
