That same year, a research study from South Korea evaluating the initial ratio (3:1 vs. 4:1) of the traditional ketogenic diet in a similar randomized, crossover design found identical results. A 4:1 initial ketogenic diet ratio was correlated with a higher likelihood of seizure freedom (55% vs. 31%, p<0.05), although ketosis at 3 months was not different. After 3 months, reducing to 3:1 did not lead to reduced seizure control in any of their children.
