Redshift evolution of the fraction of galaxies with observed EW₀ > 25 Å. Results from this work are shown as orange circles. No correction for Lyα slit losses was applied. Error bars were computed using binomial statistics following Gehrels (1986). Colored points represent JWST estimates (Nakane et al. 2024; Napolitano et al. 2024; Tang et al. 2024b; Jones et al. 2025; Kageura et al. 2025), while open symbols with black edges correspond to ground-based literature results (Stark et al. 2011; Tilvi et al. 2014; De Barros et al. 2017; Pentericci et al. 2018b; Mason et al. 2019; Fuller et al. 2020; Kusakabe et al. 2020; Tang et al. 2024a). Data points have been slightly shifted in redshift for clarity.
