The effect of pre-competition training on biochemical indices and immune function of volleyball players.
Article in International journal of clinical and experimental medicine, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
objectivePre-competition sports training can have varying effects on an athlete's immune function, including causing reduced resistance. The aim of this study was to explore effects of pre-competition training on some biochemical indices and immunologic functions in top-level volleyball athletes to determine whether training should be modified for optimal health.
methodsBiochemical indices (Hb, BUN, CK, LDH) and immunologic function (IgA, IgG, IgM, CD3(+), CD4(+), CD8(+)) were detected by semiautomatic biochemistry analyzer, light scattering photometer, or flow cytometry in sera from 24 top-level volleyball athletes and compared before and after pre-competition training.
resultsAfter training, the levels of Hb, IgA, IgG, IgM, and CD4(+) and the CD4(+)/CD8(+) ratio decreased significantly, while BUN, CK, LDH, and CD8(+) increased significantly (P < 0.05). Further, the decrease in Hb levels in female athletes was more significant than that in male athletes (P < 0.05).
conclusionsThese results indicate that pre-competition training affects biochemical indices and immunologic function in this group of athletes. Additionally, more dramatic changes in Hb in female athletes may indicate a need for adapted training loads and rest periods for females.
