Krieger, J. W. (2010). Single versus multiple sets of resistance exercise: A meta-regression. Journal of Strength and Conditioning Research, 24(4), 1150-1159.
This meta-analysis found that multiple sets lead to ~40% more muscle growth compared to a single set.

Concluded that higher training volumes (≥10 weekly sets per muscle group) produce greater hypertrophy.

Found that strength and hypertrophy improve as volume increases up to a certain point.

Discusses the mechanisms of hypertrophy and the role of training volume.

Provides guidelines for resistance training and muscle growth.

Found that low-volume training still leads to substantial hypertrophy but not maximal growth.
Heaselgrave, S. R., Blacker, S. D., et al. (2019). Effects of resistance training frequency on hypertrophy and strength: A systematic review. Sports Medicine, 49(12), 1935-1947.
Concludes that training a muscle 2–3 times per week is more effective than once per week for hypertrophy.
