How this was studied
A meta-analytic synthesis — it pools many primary studies rather than running a single design, so there is no single-study diagram.

In the authors’ words
The article’s own abstract.
This study provided a comprehensive examination of the full range of transformational, transactional, and laissez-faire leadership. Results (based on 626 correlations from 87 sources) revealed an overall validity of .44 for transformational leadership, and this validity generalized over longitudinal and multisource designs. Contingent reward (.39) and laissez-faire (-.37) leadership had the next highest overall relations; management by exception (active and passive) was inconsistently related to the criteria. Surprisingly, there were several criteria for which contingent reward leadership had stronger relations than did transformational leadership. Furthermore, transformational leadership was strongly correlated with contingent reward (.80) and laissez-faire (-.65) leadership. Transformational and contingent reward leadership generally predicted criteria controlling for the other leadership dimensions, although transformational leadership failed to predict leader job performance.

supports “The primary attributes of a transformational leader encompass providing personalized attention, encouraging intellectual growth, inspiring motivation, and embodying idealized influence (Judge & Piccolo, 2004).”
supports “…meta-analytic evidence show that transformational leadership was positively related to leader effectiveness (ρ = .79, Hoch et al. 2018; ^ p = .64, Judge and Piccolo 2004), and one meta-analysis showed that transformational leadership behaviours accounted for 8.4% of the variance in leader…”
supports “However, research has shown that transformational leadership often leads to higher levels of satisfaction, performance, and motivation among followers compared to transactional leadership (Judge & Piccolo, 2004).”
supports “Transformational leaders inspire employees through a compelling vision and intrinsic motivation, which can increase their engagement and reduce the temptation to engage in cyber-slacking (Judge & Piccolo, 2004).”
disputes “Judge and Piccolo (2004) demonstrated that transformational leadership positively contributed to job satisfaction.”
supports “Judge and Piccolo (2004) found that transformational leaders enhanced employees’ job performance and commitment through job satisfaction.”
