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
purposeBy introducing the grey correlation theory to evaluate the implementation effect of various techniques and tactics of athletes, to conduct a substantial verification of the constructed "New Four-phase Index Statistical Method", to explore the scientific nature of the division of each Phase index, and to provide theoretical support for subsequent systematic research and improvement of the theoretical research system of table tennis techniques and tactics.
methodsBy employing research methods such as video analysis, mathematical statistics, and grey correlation, a model of the "New Four-phase Index Statistical Method" was constructed. According to the contribution rate and total contribution rate indicators of the set tactics in the attack-after-serve phase (serve and 3rd stroke), attack-after-receive phase (receive and 4th stroke), transition phase (5th and 6th stroke) and rally phase (I and II) within the statistical model, the quality characteristics of the eight technical and tactical contributions of player T when playing against the main and reserve players of China were evaluated and analyzed.
resultsthe contribution rate of the first four strokes is closely related to the total contribution rate, which is the main scoring method for T to win the match. T's 5th and 6th strokes play an important role in the game of attack and defense transition, which is a key turning point of his attack-after-serve phase and attack-after-receive phase into the rally phase. The correlation between the contribution rate during T's rally phase and the overall contribution rate is not very close; similarly, the correlation between T's contribution rate and the total contribution rate is not very close either. With the multi-strokes confrontation, the advantage shown in the match began to decrease slowly.
conclusionBy introducing grey relational analysis (GRA), the various technical and tactical effectiveness of the constructed "New Four-Phase Index" can be objectively, reasonably and accurately evaluated, which has certain practicality and feasibility.
