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
Introduction: Biological maturation is a crucial aspect when assessing performance in young athletes. The maturity offset, indicating the time relative to Peak High Velocity (PHV), can impact aerobic and anaerobic capacity, as well as absolute and relative power outputs. This study investigated how maturity offset affects Peak Power Output (PPO) during the power-cadence test and Maximum Power Achieved (MPA) during an incremental ramp test in young off-road cyclists. Methods: Twenty-two young off-road cyclists (15 m, 7f) were recruited. The maturity offset of each participant was calculated using the Mirwald's predictive equations for boys and girls. A bike fitting was performed on their own bikes installed on a specific bike roller to optimize joint function. Before testing, participants were asked to warm-up for 10 min at self-selected pedalling intensity and cadence. Then, they performed a power-cadence test which consisted of five maximum sprints, each lasting 6 s, using different gear ratios. Later, participants were asked to perform an incremental ramp test with an initial power output of 2.8 W*kg-1, increasing by 10 W*min-1 until exhaustion. Results: Our results showed that the maturity offset was a significant predictor of the PPO ( Conclusion: Maturity offset appears to be a strong predictor of absolute PPO and MPA rather than relative PPO and MPA. This suggests that maturity status mainly affects aerobic and anaerobic absolute power. However, early mature status is not necessarily associated with higher performances compared to peers with late mature status. The use of maturity offset can be an effective technique for contextualizing performance in youth, as well as for monitoring the biological developmental trajectories of young athletes.
