Key: snd = survey not done, ir = irrelevant
(..) = 5-year trends only

1 0 = major problems with questionnaire or the proportion of insufficient data is high
1 = some concern with questionnaire or with insufficient data
2 = no problems with questionnaire or the proportion of insufficient data is low

2 0 = the question was not asked in one or several surveys, OR there is a more than 10% change in the proportion of "yes"-answers in the RUA between surveys and no confirmation received from the MDC that the changes are real
1 = there is a 5-10% change in the proportion of "yes"-answers in the RUA between surveys and no confirmation received from the MCC
2 = no problems with trend estimates

3 high proportion of insufficient data explained (see Section 4.2)
