In the original article, there was a mistake in Table 2 as published. The total number of one reference was wrongly included in the calculation of the endpoint efficacy over 70%. Where it reads 83/430, it should be 83/311, therefore 27% (instead of 19%). The corrected Table 2 appears below.

TABLE 2

Table 2. Efficacy of treatments in the reduction of convulsive seizures (heterogeneous population).

In the original article, there was a mistake in Table 4 as published. Data from one reference was missing in the calculation of the endpoints mild AE and severe AE. Where it reads 285/663, it should be 308/663, therefore 46% (instead of 43%). Where it reads 64/487, it should be 64/483. The corrected Table 4 appears below.

TABLE 4

Table 4. Negative secondary effects of treatment with CBD-rich Cannabis extracts and purified CBD described as secondary endpoints in the clinical studies.

In the original article, due to the errors in Tables 2, 4 mentioned above, corrections have been made to the Abstract as well as the Results, paragraphs one, two, three and five:

- “81/223, 36%” changed to “81/175, 46%” in Abstract and Results, paragraph one.

- “p = 0.56” changed to “p = 0.52” in Abstract and Results, paragraph two.

- “97/255, 38%” changed to “122/330, 37%” in Abstract and Results, paragraph two.

- “6.1 mg/kg/day” changed to “6.0 mg/kg/day” in Abstract and Results, paragraph two.

- “27.1 mg/kg/day” changed to “25.3 mg/kg/day” in Abstract and Results, paragraph two.

- “(109/285 vs. 291/346, p < 0.0001) and severe (23/285 vs. 77/346, p < 0.0001)” changed to “(158/216, 76% vs. 148/447, 33%, p < 0.001) and severe (41/155, 26% vs. 23/328, 7%, p < 0.0001)” in Abstract and Results, paragraph five.

- “17.7 mg/kg/day” changed to “15.0 mg/kg/day” in Results, paragraph two.

- “18%” changed to “27%” in Results, paragraph three.

- “83/430” changed to “83/311” in Results, paragraph three.

- “(Table 4)” changed to reference “(11)” in Results, paragraph five.

The authors apologize for this error and state that this does not change the scientific conclusions of the article in any way. The original article has been updated.
