Effects of 4-week astaxanthin supplementation on athletic performance and body composition in young male taekwondo athletes: a randomized, double-blind, placebo-controlled trial.

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
Astaxanthin is an orange-colored natural antioxidant abundantly found in crustaceans and microalgae. It exhibits diverse physiological and protective properties, including anti-inflammatory and antioxidative effects, which make it a promising ergogenic supplement for athletes. This study aimed to investigate the effects of 4 weeks of daily astaxanthin supplementation (12 mg/day) on physical performance and body composition in young male Taekwondo athletes. A randomized, double-blind, placebo-controlled design was employed to ensure the reliability of outcomes. The results showed that astaxanthin supplementation did not produce significant changes in body composition variables such as muscle mass or body fat mass. However, compared with the placebo group, athletes who received astaxanthin exhibited greater improvements in sport-specific kicking performance. Double jump kick performance increased from 67.2 ± 1.8 to 70.1 ± 2.5 kicks/20 s in the astaxanthin group, whereas it remained essentially unchanged in the placebo group (67.9 ± 2.5 to 66.9 ± 2.7 kicks/20 s). Between-group differences in double jump kick performance became statistically significant from week 1 onward and were maintained through week 4 (
