In “Associations Between Digital Health Intervention Engagement, Physical Activity, and Sedentary Behavior: Systematic Review and Meta-analysis” (J Med Internet Res 2021;23(2):e23180) a character display error was noted in 3 tables.

The “gamma” symbol (γ) was not properly rendered in 5 places in the paper due to an XML conversion error.

In Table 4, row “Rebar et al,” column “Association”:

=0.51 (95% CI −1.77 to 2.72); P>.05

has been corrected to:

γ=0.51 (95% CI −1.77 to 2.72); P>.05

In Table 5, row “Rebar et al, Time,” column “Association”:

=2.33 (95% CI 0.09 to 4.64); P<.05

has been corrected to:

γ=2.33 (95% CI 0.09 to 4.64); P<.05

and:

=0.51 (95% CI −1.77 to 2.72); P>.05

has been corrected to:

γ=0.51 (95% CI −1.77 to 2.72); P>.05

In Table 5, row “Rebar et al, Logins,” column “Association”:

=3.18 (95% CI 1.15 to 5.07); P<.05

has been corrected to:

and:

=2.04 (95% CI 0.29 to 3.84); P<.05

has been corrected to:

γ=2.04 (95% CI 0.29 to 3.84); P<.05

The correction will appear in the online version of the paper on the JMIR Publications website on March 29, 2021, together with the publication of this correction notice.
