The Effects of a 2-hour Surfing Session on the Hydration Status of Male Recreational Surfers.

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
Surfing is a popular sport globally which is performed in varied environmental conditions. With limited research in the field exploring hydration, monitoring the effect of surfing on subject hydration is warranted. The purpose of this study was to determine the relationship between surfing intensity and hydration status. A total of ten recreational male surfers were recruited for this study where hydration status was assessed pre-and post-surf session by measures of body mass (BM) and urine specific gravity (USG). Intensity of the surf session was quantified by Global Positioning Systems and Heart Rate monitoring. Subjects surfed for two hours and covered an average distance of 4974.18 ± 542.62 m, with an average speed of 2.48 ± 0.27 km/h and peak speed of 31.86 ± 3.51 km/h. A statistically significant decrease in absolute and relative BM was observed (0.70 ± 0.4 kg,
