1 · What the graph read from it

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.

2 · The registry

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

Purpose: The purpose of this study was to quantify return-to-play (RTP) time, post-operative performance and market-value trends after proximal hamstring repair in top-tier European league soccer players. It was hypothesized that surgery would achieve a high RTP rate but be accompanied by reductions in player performance and valuation. Methods: Male first-team players from the five major European leagues who underwent surgical repair of proximal hamstring ruptures between 2019 and 2022 were identified collaboratively with the InjuryMechanisms platform. Publicly available data (Transfermarkt) was accessed to extract demographics and season-by-season metrics for two seasons before and two seasons after injury. Outcomes were RTP time, matches missed, percentage of minutes played per season (MPS), goals, assists and market value. Non-parametric Friedman test with Dunn-Bonferroni post hoc test assessed longitudinal changes. Results: Twenty players (mean age, 25.3 ± 4.4 years) met the inclusion criteria. All returned to professional competition without reoperation. Mean RTP was 160 ± 76 days, with 21.5 ± 11.5 matches missed. Goals and assists were unchanged across seasons ( Conclusion: Surgical repair of proximal hamstring rupture allowed reliable return to competition in elite soccer players, with preserved performance. However, players experienced a transient, non-significant reduction in competitive involvement during the first post-operative season and market value significantly declined despite favourable performance outcomes. Level of Evidence: Level IV.
