All authors have made an intellectual contribution to this research trial.
While measurement in any new field can no doubt be improved, we do not think instrumentation challenges made a major contribution to this negative trial.
All authors made a substantial contribution to the trial protocol.
If the contribution to the trial of most people goes unrecorded, so does their individual responsibility for what is produced.
A simpler model than that used here would have excluded some factors and could not determine their contribution to the trial's lack of detectable population-level impact.
We thank all women who participated in the trial, the trial staff at clinical centres, and the staff at the National Institute for Health and Welfare in Finland and at the Institute for Health Development in Estonia for their contribution to the trial.
This randomised controlled trial is an important contribution to this debate as it is the first to apply well validated and concurrent assessments of gastric emptying, alcohol concentrations, and postprandial symptoms.
Other individuals who make substantial contributions to the trial will be acknowledged at the discretion of the writing committee.
Karen Ball, research assistant (RA), (RUH), Sally Harries (RA, PHFT), Deborah Randall (RA, PHFT, Susan Smithh (RA, PHFT), Rachael Skinner (RA, RUH), Clare Fox (RA, RUH), Rachel Humphrey, Research Nurse PHFTT) and Susara Blunden (RA, PHFT) have made contributions to the trial.
Participants can be said to make an essential contribution to their trial in two senses.
