“…Twenty‐three studies (Abrahams et al, 2017; Bantum et al, 2014; Boele et al, 2018; Foster et al, 2016; Freeman et al, 2015; Huberty et al, 2019; Jim et al, 2020; Kearney et al, 2009; Kubo et al, 2019; Ligibel et al, 2012; Ream et al, 2015; Ritterband et al, 2012; Shi et al, 2015; Smith et al, 2019; Somers et al, 2018; Spahrkas et al, 2020; Steel et al, 2016; Vallerand et al, 2018; van den Berg et al, 2015; Willems et al, 2017; Yun et al, 2012; Zachariae et al, 2018; Zhou et al, 2020) evaluated the effectiveness of eHealth interventions on CRF. The pooled result showed a small effect of eHealth interventions on CRF, and the improvement was not statistically significant (SMD = −0.16, 95% CI: −0.33 to 0.01, p = 0.07; I 2 = 79%, p < 0.00001) (Figure S8).…”
