Involvement of LMC authors or participating centres stratified by funding source is illustrated in Figure 3.
Disagreements were resolved by discussion and, where necessary, through the involvement of additional authors.
In addition, the involvement of chapter authors from a variety of fields including family psychology, family sociology, child development, family studies, public health, and family therapy, gives the Handbook a multidisciplinary and interdisciplinary framework.
Two authors (DHST, KM) independently assessed studies for inclusion in an unblinded standardized manner, and independently extracted data onto standardized forms, with disagreements resolved by consensus and involvement of other authors.
Triangulation (Charmaz, 2006; Creswell, 2007) was applied to further enhance reliability through the involvement of all authors in the analysis, the use of multiple sources of data and several interviewers.
Some important strengths of the trial include cluster randomisation of clubs to avoid contamination between the intervention and control groups, individual playing time registration with no missing data for analysed clubs, careful monitoring of compliance, blinded analysts, and no involvement of the authors in the development of the programme.
Any disagreements with authors (GCL and SMW) were resolved by discussion and the involvement of another author (LW).
But the involvement of co-authors can vary wildly.
This paper is motivated by a recent involvement of the author in a forensic investigation on the response of cantilever tubular highway poles during a particular winter storm and, in general, unforeseen and extreme wind events.
