Confounds, systemic or otherwise, introduced in a study design cannot be recorded or tested using multivariate classification methods in as flexible a fashion as in (e.g.,) general linear models [Todd et al., 2013].
It was assumed that all studies used the National Glycohemoglobin Standardization Program (NGSP) HbA1c reference, unless explicitly stated otherwise in a specific study.
Otherwise, in a vignette study, a consensus seemed to exist across GPs, non nephrology specialists and nephrologists about recognizing that dialysis was not appropriate for elderly patients under some circumstances such as terminal cancer, but still on debate about other co-morbidities, such as mild shortness of breath, diabetes and mild cognitive impairments [ 37].
We designed the study and approached the data with a specific interest, and may have overlooked phenomena that would otherwise have been described in a study with a broader aim.
The rest of the authors declare that we do not have any conflict of interests, financial or otherwise, in this study.
Otherwise, in most studies, only overall expression and methylation levels are examined (Tables 1 and 2).
These BDs may not have been otherwise detected in a passive surveillance study.
The relatively small sample size could influence statistical power (especially when categorical variables were used) for multivariate analysis and there is a possibility of missed associations which could otherwise be detected in a larger study group.
Randomisation was performed by an individual not otherwise involved in the study using a computer-based random number generator.
Following completion of the randomized control study, a chartered counselling psychologist (AE), who had not otherwise participated in the study, interviewed a random sample of eight individuals who had been in the singing arm of the trial.
