Cost-effectiveness of treatments for presymptomatic newborn patients with spinal muscular atrophy and two or three copies of the survival motor neuron 2 gene in Italy.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveWe assessed the cost effectiveness of onasemnogene abeparvovec (OA) for presymptomatic infants with two or three copies of the survival motor neuron 2 (SMN2) gene (diagnosed/treated ≤ 6 weeks old) who lack functional SMN1 gene (biallelic SMN1 mutations). This cost-utility model compared three disease-modifying treatments and best supportive care (BSC) (scenario analysis) in an Italian setting.
methodsFor a cohort of 1000 children, a Markov model simulated costs and benefits of OA (a one-time treatment), nusinersen and risdiplam (continuous lifelong treatments), and BSC. A lifetime time horizon (up to age 100 years) was applied, and the perspective of the Italian National Health Service was considered. Results are reported as incremental cost-effectiveness ratios (ICERs). Deterministic and probabilistic sensitivity analyses were conducted to assess the robustness of the model and validity of results.
resultsIn the full cohort, OA was dominant (less costly, more effective) compared with nusinersen or risdiplam (ICERs,-€4,562,815 and-€718,640), and cost effective (more costly, more effective) compared with BSC (ICER, €65,894). Similar results were found for patients with two SMN2 copies. For patients with three SMN2 copies, OA was less costly, with a similar efficacy profile compared with nusinersen, dominant versus risdiplam, and cost effective compared with BSC. Probabilistic sensitivity analysis demonstrated the robustness of the model and validated deterministic sensitivity analysis results for the full cohort.
conclusionsOA for the treatment of presymptomatic newborns was dominant or cost effective compared with other treatments or BSC in the full patient cohort within the Italian context.
