The Effect of L-Tryptophan Intake on Dynamic Strength in Paralympic Powerlifting.
Article in International journal of tryptophan research : IJTR, 2026. 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
Introduction: L-tryptophan supplementation has been studied in endurance sports with controversial results, and its influence on maximal strength sports remains largely unexplored. This study investigated whether L-tryptophan supplementation improves dynamic strength indicators in Paralympic powerlifting athletes. Methodology: A randomized, double-blind, crossover clinical trial was conducted with 13 paralympic powerlifting athletes. The athletes were supplemented with L-tryptophan or placebo for 72 hours before training. Strength was assessed using an encoder, measuring mean propulsive velocity (MPV), maximal velocity ( Results: L-tryptophan supplementation resulted in higher MPV, Conclusion: L-tryptophan supplementation appears to temporarily improve pre-exercise strength performance in Paralympic powerlifting athletes, possibly by influencing neuromuscular relaxation.
