Ici, l'alerte incite le médecin à faire un test simple (une prise de sang) et, si le résultat est élevé, à proposer un suivi spécialisé.

This hypothesis proposes the use of a simple score (FIB-4) and alerts within the medical record to identify at-risk patients, followed by referral to dedicated consultations. The objective is to increase the number of patients correctly monitored or referred to a specialist by 25 to 40 per cent within 12 months.",
    "why_it_matters": "Hepatic steatosis affects approximately 25% of the global population and can progress to cirrhosis or liver cancer. At present, many patients are neither screened nor followed up, owing to a lack of time and simple tools in primary care. This approach, integrated into the medical record, could improve management without high costs and reduce long-term complications. It would benefit diabetic, obese, or hepatically abnormal patients, who are at greatest risk.",
    "imagine_that": "Imagine that your general practitioner, during a consultation, receives an alert on the screen: “This patient has a risk of hepatic fibrosis, check their FIB-4 score.” It is a little like an automatic reminder in a running app: it encourages you not to forget your training session. Here, the alert prompts the doctor to perform a simple test (a blood draw) and, if the result is high, to propose specialised follow-up. This ensures that no one is left behind, like a safety net that deploys at the right moment.",
    "reviewers_say": "The panel is broadly favourable, with a mean score of 6.5/10. The strengths: the approach is pragmatic, builds on tools already available (FIB-4, the medical record) and addresses a genuine clinical need. The three-phase method is judged rigorous and reduces risk. Reservations are, however, expressed: the 25–40% effect appears optimistic to some, as computerised alerts are frequently ignored (alert fatigue) and clinicians lack time. Moreover, the protocol does not specify how contamination between groups is to be avoided, nor how the sample size is to be calculated. The verdict: a pilot study must first be conducted to verify the feasibility and fidelity of the intervention before a large trial is launched.",

The hypothesis is judged to be testable within this framework, and the panel notes that the phased approach permits iterative refinement prior to full-scale deployment.\n\nPhase 2 involves a panel review of the interim findings, with the meta-reviewer verifying all results through Semantic Scholar. The domain-specific hypotheses are analysed against the available evidence, and the collision of findings across domains is examined for convergent validity.\n\nPhase 3 is centred on the full cluster RCT, for which funding is sought from the Horizon Europe 'Health' pillar or national agencies. The panel notes that the kill rate for the intervention, as measured in the pilot phase, will inform the power calculations for the larger trial. The briefs for each phase are maintained as separate documents, with the panel reviewer responsible for their oversight.\n\nThe behaviour of the intervention is modelled across the three phases, with the primary outcome being the health system impact.
