Q: What correction was made to Table 2 in the original article?

The data in Table 2 were incorrectly presented and the corrected Table 2 is provided, showing the percentages of completed modules/sessions with and without parental support and including missing-data counts.

Q: How was missing time-to-event data handled in the Kaplan-Meier analysis?

Participants with missing time-to-event data were excluded from the Kaplan-Meier analysis, and the updated Methods text now states this under Data Analysis.

Q: Were the underlying data or results changed after updating Figure 2?

No changes were made to the underlying data or results; Figure 2 was updated for clarity and to match the revised Methods regarding exclusion of participants with missing time-to-event data.

Correction notice for a JMIR publication addressing specific presentation and reporting errors. Table 2 was incorrectly presented and is replaced with the corrected distribution of completed iACT modules or sessions with and without parental support, including handling of missing data counts. The Methods section was also updated to clarify exclusions of participants with missing time-to-event data in Kaplan-Meier analysis and to improve Figure 2 clarity, without changes to underlying data or results. The corresponding author’s email was updated and the correction is described as resubmitted to full-text repositories.

To address this, the following sentence has been added to the Methods section under “Data Analysis” on page 18: “Participants with missing time-to-event data were excluded from the Kaplan-Meier analysis”. The corrected version of that excerpt now reads: Due to a nonrandomized design, a small sample, a large dropout, and the fact that no a priori power analysis was made, the data are nonparametric, which makes between-group comparisons less meaningful. Therefore, the TAU group (n=11) is not included in this evaluation. Adherence was analyzed using descriptive data andMeier-Kaplan survival analysis, a statistical method used for measuring the distribution of time of occurrences in cohort groups [37].
