§2.2Arms

Table 2. Randomised arms. Illustrative: arm-level allocations are reconstructed by the Institute from the design class and the randomised total where the published report does not state them.

Indication. Primary mitochondrial myopathy and bioenergetic disorders

Genetically determined impairment of oxidative phosphorylation producing myopathy, exercise intolerance or multisystem disease.

Geographic footprint. Germany · Netherlands · France · Republic of Korea · China.

§2.4Eligibility as the Institute reads it

  • Included. Genetically determined impairment of oxidative phosphorylation producing myopathy, exercise intolerance or multisystem disease.
  • Excluded. Participants for whom the intervention is contraindicated, including not established — no marketing authorisation. Exclusion criteria narrow the population to which the estimate applies and are the principal source of indirectness where a trial estimate is applied to ordinary practice.
Nothing published by the Institute is medical advice, a diagnosis, a prescription, a treatment recommendation or a purchasing recommendation. Compounds supplied for research use are not approved for human or veterinary use in any jurisdiction, and a favourable analytical assessment of a supplier is not a statement that any product is safe or effective. The Institute publishes certainty ratings and never recommendations. No telephone number, messaging handle or ordering channel appears anywhere on this site.
