Study	Reason for exclusion
Astle 2011	Perceptual learning to reduce stereo deficits. Adults; review article; no randomisation
Bau 2012	Stimulation therapy: drifting sinus grating combined with computer games; better‐seeing eye occluded during treatment, so treatment not binocular
Birch 2020	Insufficient follow‐up interval (too short)
Chen 2008	Perceptual learning approach, grey‐level gratings, Gabor patch contrast detection task. Better‐seeing eye occluded during treatment, so treatment not binocular; no randomisation
Foss 2013	None of the treatment groups received an occlusion or blurring treatment
Gambacorta 2018	Insufficient follow‐up interval (too short)
Gao 2018	None of the treatment groups received an occlusion or blurring treatment
Herbison 2016	None of the treatment groups received an occlusion or blurring treatment
Ide 2013	Treatment not for amblyopia
Kampf 2001	Stimulation therapy: drifting sinus grating combined with foreground game. Better‐seeing eye occluded during treatment, so treatment not binocular
Kelly 2016	Study time points not compatible with Cochrane protocol (8 or 16 weeks).
Lennerstrand 1983	Stimulation therapy: grating; full‐time occlusion. Better‐seeing eye occluded during treatment, so treatment not binocular
Rajavi 2019	Insufficient follow‐up interval (too short)
