In the original article, there was a mistake in Figure 1 as published. An entry was labelled as “No adherence” rather than “Disease progression”. The corrected Figure 1 appears below.
Figure 1 CONSORT Diagram. Updated from Stupp R, Taillibert S, Kanner A, Read W, Steinberg DM, Lhermitte B, et al. Effect of tumor-treating fields plus maintenance temozolomide vs maintenance temozolomide alone on survival in patients with glioblastoma a randomized clinical trial. JAMA. (2017) 318:2306–16 TMZ, temozolomide; TTFields, Tumor Treating Fields.
In the original article, there was also a mistake in Table 2 as published. Incorrect data appears for Duration of TTFields therapy, months, median (range) and TTFields daily usage ≥75%, n (%) for TTFields plus TMZ. The corrected Table 2 appears below.
Table 2 Baseline characteristics in TTFields (200 kHz) plus TMZ combination versus TMZ monotherapy groups for patients ≥70 years of age.
In the original article, there was a further mistake in Figure 3C as published. There was an error in KPS, median (range) for TTFields (200 kHz) ≥75% Daily Usage. The corrected Figure 3 appears below.
Figure 3 Kaplan–Meier curves of (A) median PFS and (B) median OS of TTFields plus TMZ combination with TTFields daily usage of ≥75% (purple lines) compared to TTFields daily usage of <75% (green lines) and TMZ alone (red lines). (C) Baseline age and KPS of patients ≥65 years of age with TTFields daily usage of ≥75% and <75%. CI, confidence interval; KPS, Karnofsky Performance Status; mo, month; no, number; OS, overall survival; PFS, progression-free survival; TMZ, temozolomide; TTFields, Tumor Treating Fields.
