Finally, although our overall sample was relatively large, survey participation at study onset was not very high in some countries (e.g. Switzerland) and, thus, we cannot rule out that an unobserved selection bias affects our findings.
For the United Kingdom, evaluations of the pilot implementation of a means tested conditional cash transfer (Educational Maintenance Allowances (EMAs)) paid to the student show relatively large changes in participation in post-compulsory education in the ' treated' group, particularly for those with the lowest prior achievement ((Dearden et al. (2009)).
To facilitate participation by this relatively large number of participants, it was also agreed to adapt the workshop design by introducing complementary methods from the repertoire of the Nominal Group Technique.
The preparation of background information of hazard-affected elements included in the quantitative assessment index system by visual interpretation from remote sensing data often requires the participation of relatively large numbers of personnel.
Consistent with other research [15], Table 3 shows that, in addition to an increased level of overall service utilization, countries with a relatively large share of private sector participation tend to also have significantly higher levels of maternal education and also higher levels of GDP per capita, although differences in per capita income are not statistically significant.
Accordingly, the dropout before actual study participation was relatively large.
The observation that small and medium-sized enterprises and micro enterprises are involved in a relatively large number of standards indicates that participation in standardisation in W3C is open and inclusive.
Providing computer-tailored feedback that was endorsed by the patient's GP might have contributed to the participation of a relatively large cohort.
Second, the study sample was relatively large and has a very high participation rate, supporting the generalizability of our findings to the population of French breast cancer survivors.
Among the strengths of the study are the relatively large sample size, the almost complete participation of cases and controls, the comparable catchment areas of study subjects, and the accurate control for major recognised risk factors for pancreatic cancer.
