Of the 25 patients in the post hoc analysis, 4 experienced 9 acute TTP events while receiving PBT prophylaxis.</p><p><strong>Conclusions: </strong>Our findings suggest that acute TTP events occurred less frequently during periods of prophylaxis but also highlight prophylaxis' intrinsic limitations in preventing ongoing manifestations, cumulative organ damage, and the logistical and safety burdens associated with repeated plasma infusions. Patients with cTTP bear a substantial clinical and disease burden associated with acute TTP events and organ damage. Despite treatment with PBT prophylaxis, some patients still experienced acute TTP events, suggesting that more effective treatments may be needed.</p>","PeriodicalId":16012,"journal":{"name":"Journal of Health Economics and Outcomes Research","volume":"13 2","pages":"55-66"},"PeriodicalIF":2.5,"publicationDate":"2026-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13476067/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148759380","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

AI was used to screen titles/abstracts, screen full texts, and conduct data extraction. Using the traditional SLR as the benchmark, AI performance for title/abstract screening was evaluated in terms of accuracy, recall, and precision at predefined screening milestones, followed by the accuracy assessment of full-text screening by AI. Data items extracted by AI were verified by humans and categorized as correct, incomplete, missing, incorrect, or requiring human checks. The average accuracy rate calculated on the basis of correct data items extracted was used as an indicator of AI performance in data extraction.</p><p><strong>Results: </strong>During title/abstract screening, accuracy and recall remained high but precision was low, increasing false positives. Full-text screening identified a minority of studies included in the traditional SLR. Mean extraction accuracy was 72.93% (range, 57.69%-88.46%).
