Measures of adherence Data are collected on the number of intervention visits attended in the two active intervention groups, including any individual make-up sessions attended and individual "red-zone" counseling sessions.
Plasma was collected on the day before surgical intervention and stored at −80°C.
Data were also collected on the time taken by intervention facilitators to train the nurses and to provide feedback.
However, repeated observation of the intervention, data collected on the action plans, and exchanges held with some participants provided the researchers with in-depth knowledge of the intervention's action mechanisms and allowed coherent changes to be made to the intervention.
In some cases this may not be possible, for example, it is not appropriate to extrapolate clinical trial results for respiratory viruses to tuberculosis and for ethical reasons, randomised trial data cannot be collected on the effectiveness of a respirator intervention in HCWs for tuberculosis prevention.
We also collected data on the intervention (pharmacological or nonpharmacologic treatment) and the number of participating countries.
We also collected data on the intervention implementation process from selected staff at each clinic.
Data were collected on design, intervention characteristics, target group, recruitment methods, delivery mode, number of sessions, attrition rates, control group, outcome measures and effect sizes (post-test and at follow up of at least 3 months).
Data on biometrics, blood measures and health behaviour will be collected on individuals in the intervention and control villages at program entry (baseline), one month, three months and six months by a team of HP's.
To explore uptake and delivery of the intervention we collected data on the interventions that participants chose, treatment uptake and attrition rates.
