Abstract NS13: YOU CALL - WE CALL Trial: Impact of a Multimodal Support Intervention After a “Mild” Stroke
Bibliographic record
Abstract
purpose: To assess the impact of a post-discharge multimodal support intervention - “WE CALL” versus a passive “YOU CALL” intervention (providing telephone contact information of a resource person) in individuals with first mild stroke. Primary outcomes were unplanned use of health services for negative events and quality of life. Secondary outcomes included planned use of health services, participation and mood. Methods: Single-blind RCT stratified on level of co-morbidity. WE CALL participants were phoned 13 times over the six month period (weekly to monthly) by a trained healthcare professional to discuss any new or ongoing issues. Blind assessments were done at baseline and at 6 and 12 months. Use of health services was collected through participant diaries. We used a mixed model approach for statistical analysis on an intention-to-treat basis where the group factor was intervention type and occasion factor time, with a significance level of 0.01. Results: We enrolled 186 patients (We = 92; You = 94) with a mean age 62.5 ± 12.5 and 41% female. There were no baseline differences between groups on the primary (Euroquol-EQ5D, Quality of Life Index) or secondary outcomes (Assessment of Life-Habits (LIFE-H), and Beck Depression Inventory II). At six months, 92% (137/149) had visited a physician while less than 20% a rehabilitation specialist. No significant differences were seen between groups at six months on any outcomes with both groups improving from baseline on all measures (effect sizes ranged from 0.2 to 0.8). The only significant change from 6 months to one year (n=139) was in the social domains (relationships, work and recreation) of the LIFE-H (increment in score=0.4/9±1.3 [95%CI=0.1-0.7]; ES=0.3). Qualitatively the WE Call intervention was perceived as reassuring, increased insight and problem solving while decreasing anxiety. In contrast, only 6/94 (6.4%) of YOU Call participant availed themselves of intervention. Conclusion: While the two groups improved equally over time, some of the WE CALL intervention key features, which will be described, were reported to be very helpful.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
