Soccer pass performance following caffeine intake with deliberate or maintenance practice.
Trial report in Journal of the International Society of Sports Nutrition, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper, 1 of them a synthesis that pooled it.
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
backgroundThe impact of caffeine on strength and endurance performance is well acknowledged, yet its influence on skill performance remains contentious. A potential scenario in which caffeine augments the efficacy of practice could be useful for sports brokers who diligently pursue every nuance to enhance performance. Therefore, the primary objective of this study was to examine the impact of 3 mg·kg
methodsFourteen adolescent male football players (14.07 ± 0.26 years; 174.28 ± 3.12 cm; 57.21 ± 8.40 kg) participated in a double-blind, randomized, counterbalanced, and crossover research design. For the experimental protocols, each participant visited an artificial turf pitch on four occasions, separated by 48 h. They received 3 mg·kg
resultsThere was no difference in LSPT, OTPT, or LPT values following caffeine (CAF) and placebo (PLA) supplementation after DP or MP. Regardless of CAF-PLA conditions, although both practices improve the LSPT original time, penalty time, and performance time, only MP increases the LPT score (21.9%;
