Effects of Caffeine on NFL Combine-Like Tests in Undergraduate Students.

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
Caffeine is a widely used stimulant with performance enhancing characteristics. The effectiveness of caffeine in various circumstances, such as within a series of physiological assessments which utilize different energy systems, is less clear. The purpose of this research study was to determine the effectiveness of caffeine on different areas of the NFL combine-like tests, specifically the 40-yard dash (40-YD), standing broad jump (SBJ), and YMCA bench press test (YMCA-BP). Thirty-three healthy participants (19 men, 14 women: age 20.42 ± 1.23yrs) consumed a 200mg caffeine and placebo pill on two occasions. The participants were randomly assigned to which they received first and blinded to the caffeine or placebo. Forty-five minutes after taking the pill, participants performed the YMCA-BP (80lbs men, 35lbs women: 30 reps/min), the SBJ (3 attempts with best jump recorded), and ran the 40-YD (2 attempts, best recorded). Participants returned one week later, consumed the other pill, and performed the tests. Results from each trial were compared using a paired samples
