Determine if the following text contains a data availability statement. Answer with 'yes' or 'no'.

Text: A small number ( n ¼ 32 , 0.2 % ) of returned questionnaires were completely blank , thus were excluded from the analysis involving the questionnaire data ( they are included in the ITT analysis ) . Therefore , 13,645 questionnaires were included in the secondary analyses of questionnaire data . Some questionnaires were incomplete ; the amount of data missing for each individual item ranged from 0.3 % to 1.6 % . All secondary outcome measures ( i.e. , AR , intention , ICK , HLOC and perceived benefit ) were calculated as means of available items . Multiple imputation was used to estimate means for all secondary outcome measures where fewer than 50 % of items had been completed ( n ¼ 189 means , across n ¼ 137 ( 0.1 % ) of returned questionnaires ) . Multiple imputation is the current preferred method of handling missing data in clinical trials ( Graham , 2009 ) . The data were imputed via the multiple imputation routine ( fully conditional model ) in SPSS with age , gender , SIMD quintile , previous kits returned , previous failures to return kit and the remaining secondary outcome measures as predictor variables . Single iteration was performed as the amount of missing data was very small . Imputed means were constrained to within 1e7 .<|eot_id|><|start_header_id|>assistant<|end_header_id|>
