SENSITIVITY
The UC+MI arm had 6 fewer median days of sick leave compared with the UC arm (not statistically significant (ns)) and the mean difference was 7 fewer days (95% CI −16 to 2) (ns) (Unadjusted analyses. Sickness absence days over 6 months, comparison between UC and UC+MI or UC+SVAIITT, intention-to-treat analysis (five missing: three in UC arm, one in UC+MI arm, one in UC+SVAI arm).Sensitivity analysis 1: excluding pilot participants.Sensitivity analysis 2: excluding participants who returned to work ≥50% within 1 week after baseline.*Statistically significant difference (p<0.05) compared with UC only, tested with t-test or Mann-Whitney Wilcoxon test.95% CI, 95% confidence interval (estimated with 10 000 bootstrap resamples); MI, motivational interviewing; n, number of participants in analysis; SVAI, stratified vocational advice intervention; UC, usual case management.
