Lifting heavy weights until you fail makes you stronger, no matter if you do one, four, or eight sets per workout. This finding is from the abstract summary - full study details were not available.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
A systematic review would consolidate evidence on the efficacy of failure-based training across various exercises and populations to confirm its universal effectiveness for strength development.
A systematic review and meta-analysis of RCTs evaluating the impact of training to failure versus non-failure on 1-RM strength gains in resistance-trained individuals over 8+ weeks.
An RCT could isolate the specific contribution of training to failure by comparing it to matched volume training stopped at a predetermined RPE, controlling for confounding variables.
A double-blind RCT with 80 trained males randomized to 80% 1-RM squats to failure or matched volume at RPE 7, measuring 1-RM strength at baseline, 6, and 10 weeks with blinded assessors.
A prospective cohort study could track natural training practices to observe how self-selected failure training correlates with long-term strength progression in real-world settings.
A 12-month prospective cohort study of 150 resistance-trained males, tracking self-reported training to failure frequency and measuring quarterly 1-RM strength changes while controlling for age, training history, and nutrition.
