The problem
Intervention: Prolonged ketogenic diet treatment (high fat diet producing anticonvulsant and neuroprotective effects)
Who it was tested with: 26 pediatric patients with drug-resistant epilepsy, followed for over 2 years.
The same group is measured before the intervention and again afterwards, with a baseline and an endline and sometimes a midline. Change is visible, but other causes cannot be ruled out.
"Observational descriptive study of 26 pediatric patients on a KD, with data collection at baseline, at 3, 6, and 12 months, and then once a year." This is a pre-post design measuring the same group longitudinally without a comparison group, making it a PRE_POST tier study.
Small sample size of 26 children with no comparison group or control; observational design limits ability to establish causation; no detail provided on dropout rates or loss to follow-up; heterogeneity of epilepsy types and baseline severity not clearly described.
