From: Randomized crossover trial of a modified ketogenic diet in Alzheimer’s disease
Mean weekly blood (a) glucose and (b) ketone (beta-hydroxybutyrate) levels for all randomized patients (n = 26 for ketogenic diet, n = 26 for usual diet). For patients with weeks containing partial data, the days containing data were used to calculate the weekly mean. Regarding withdrawals, all data up to the point of withdrawal are shown, with regression imputation used to calculate values for the weekly means post-withdrawal. Error bars indicate standard error
