Sports Performance and Injury Epidemiology in Portuguese XV Rugby Union's 2023 World Cup Preparation in a High-Altitude Center: A Cross-Sectional Study.
Article in Journal of functional morphology and kinesiology, 2025. 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
backgroundRugby Union's physical demands lead to high injury rates, requiring players to optimize their abilities. Altitude training enhances performance but poses risks to injuries.
methodsThis cross-sectional observational study compares the Portuguese Rugby team's injury rates and Global Positioning System (GPS) performance data during the Rugby World Cup (RWC) 2023 preparation phase. Two medical doctors from the medical Portuguese department diagnosed and recorded all the injuries occurred. GPS players data recorded the following: running distance (RD), high-speed running distance (HSRD), number of accelerations of high intensity (HI), maximum velocity (MV), and percentage of personal maximum velocity (% MV). Data were analyzed by position and growth rate (∆) comparing sea level (Cycle 1) and altitude (Cycle 2). The players were analyzed by injury severity, type, anatomical location, and GPS performance metrics.
resultsA higher number of injuries was recorded in Cycle 2 compared to Cycle 1 (∆ = +5 for forwards; ∆ = +3.5 for backs). While average values for MV and % MV showed a downward trend, RD, HSRD, and HI exhibited upward trends. However, none of these differences reached statistical significance.
conclusionsInjury counts and training volume indicators showed upward trends, while MV and % MV declined, though none reached statistical significance. These patterns should be interpreted cautiously, and further research is needed to explore GPS metrics in injury monitoring.
