Corrigendum to “Complications During Ketogenic Diet Initiation: Prevalence, Treatment and Influence on Seizure Outcomes” [Pediatr Neurol. 68 (2017) 35–39](S0887899416310244)(10.1016/j.pediatrneurol.2017.01.007)

We would like to call attention to an error in our article, “Complications during ketogenic diet initiation: prevalence, treatment, and influence on seizure outcomes.” An astute reader noticed a mistake in both number and percentile in Table 5, which compared complications from a fasting versus nonfasting ketogenic diet initiation. Now no longer significant, the incidence of at least one event of hypoglycemia <40 mg/dL was 35 (27%) in those 127 fasted versus a similar 9 (29%) of those 31 not fasted (P=0.87). Adding to our other findings, there is now no difference in all studied hypoglycemia events (including repeated values <40 mg/dL or at least one <30 mg/dL). Lethargy was the only more likely complication in those fasted. We do not believe this finding changes our three main messages: complications at ketogenic diet initiation were mild and treatable, do not portend a failure of seizure control, and were more common in younger children. We agree with the European guidelines for ketogenic diet initiation in infancy which recommends against fasting in children under 2 years of age, as even lethargy alone can be problematic. The authors would like to apologize for any inconvenience caused.
