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
Objective: Although corporate sponsorship is the primary controllable revenue stream in professional esports, its strategic management-particularly regarding continuity and diversification-remains largely under-theorized. This gap is notable given the volatility and rapid commercialization of top-tier leagues. Focusing on China's League of Legends Pro League, this study examines how sponsorship portfolios are structured and sustained over time. Methods: Using 2021-2024 data from 17 clubs and the league, sponsorship continuity was quantified via Jaccard similarity coefficients and diversification via Blau indices across 25 MSCI industry categories. Results: Tencent-managed league-level portfolios were both stable and diversified, while most club portfolios were volatile and concentrated. Publicly held clubs achieved significantly greater diversification than private clubs, reflecting governance advantages. Club performance predicted greater subsequent diversification but not continuity. Positioning clubs within a continuity-diversification matrix revealed only a few in the "Strategic Resilience" quadrant, with many "At Risk." Conclusion: These findings suggest that clubs should prioritize a core set of enduring sponsors while expanding into diverse categories to reduce revenue volatility, strengthen bargaining power, and enhance resilience to market shocks. The study provides a replicable framework for evaluating sponsorship continuity and diversification, supporting evidence-based decision-making in esports managerial practice.
