Revisiting leader-member exchange: a review through the lens of the "too much of a good thing" effect.
Review in Frontiers in psychology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Objectives: This review reexamines the widely accepted belief that high-quality leader-member exchange (LMX) relationships are uniformly beneficial. Methods: Based on the "too much of a good thing" framework, this study systematically reviews new empirical evidence suggesting that excessively high LMX may yield diminishing returns and negative outcomes. Results: This review examines the unique and important contributions that high LMX relationships bring to LMX research. It highlights the emotional costs underlying non-linear patterns and presents an integrated Resource-Emotion-Motivation (REM) theoretical framework. Additionally, it discusses methodological aspects to better capture the dynamic relational process. Conclusion: Finally, based on the reviewed papers, we present the academic and practical implications for future research. This review contributes to broadening the understanding of LMX dynamics.
