Effect of high vs. low volume of the nordic hamstring curl on hamstring muscle architecture and eccentric strength in soccer players: a systematic review and meta-analysis.

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
Hamstring strain injuries (HSI) remain a significant problem in professional soccer, as this injury is the most prevalent. Nordic hamstring exercise (NHE) is the most researched exercise regarding its effect on modifiable factors of HSI. However, there is still debate about the minimal effective dosage for this exercise. This systematic review and meta-analysis aimed (1) to analyse the effects of low- and high-volume NHE on eccentric strength and hamstring muscle architecture in soccer players, and (2) identify gaps in the literature to guide future research. Three electronic databases (PubMed, Web of Science, Scopus) were searched, and 11 studies met the inclusion criteria. Pooled effect sizes (Hedges' g) and 95% confidence intervals (CI) were calculated using a random-effects model. High-volume NHE interventions significantly improved eccentric hamstring strength (g = 0.77, 95% CI 0.49-1.06, p < 0.001, I
