Categorization of evidence and basis of recommendation Ia from meta-analysis of randomized controlled studies, Ib from at least one randomized controlled study, IIa from at least one controlled trial without randomization, IIb from at least one other type of quasi-experimental study, III From nonexperimental descriptive studies, such as comparative, correlation, or case-control studies, IV From expert committee reports or opinions or clinical experience of respected authorities or both. Strength of recommendation A based on category I evidence, B based on category II evidence or extrapolated from category I evidence, C based on category III evidence or extrapolated from category I or II evidence, D based on category IV evidence or extrapolated from category I, II, or III evidence. IVIG: Intravenous immunoglobulin; AES: Acute encephalitis syndrome; ADEM: Acute disseminated encephalomyelitis; ALERD: Acute leukoencephalitis with restricted diffusion; ANEC: Acute necrotizing encephalopathy of childhood; FIRES: Febrile infection related epilepsy syndrome; MODS: Multiorgan dysfunction syndrome; SE: Status epilepticus.
