Exploring the key points and key shots in table tennis matches based on survival analysis.
Article in PloS one, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
This study aimed to investigate the Key Points (KP) and Key Shots (KS) in singles matches for elite table tennis players, enhancing the knowledge of winning patterns in table tennis. A total of 60 men's singles and 64 women's singles matches were analyzed, all data sourced from events such as the World Championships, World Cup, Olympic Games, and WTT Champions.
methodsSurvival analysis was introduced, in which points scored in a match and shot counts in a rally were treated as "survival time," while losing a point was defined as the "event." The Kaplan-Meier method was employed to estimate cumulative survival probabilities, which reflect the likelihood of players enhancing their winning potential at specific scores or shot numbers. The point or shot number at which the cumulative survival probability drops to 50% is defined as the KP or KS, respectively. Additionally, the Log-rank (Mantel-Cox) non-parametric test was applied to determine whether significant differences existed between the survival curves of different groups.
resultsKP in table tennis singles demonstrate a stable pattern of " 7 for women, 8 for men," while Winning Points (WP) are predominantly concentrated at the 9th point. The KS positions are consistent in both men's and women's singles, specifically the 4th shot in the total rally, the 3rd shot in the serving round, and the 2nd shot in the receiving round. Winning Shots (WS) consistently occur at the 6th shot in the total rally, as well as the 3rd shot in both the serving and receiving rounds.
conclusionThese findings advance our understanding of winning patterns in table tennis, providing theoretical foundations and practical references for designing contextualized training programs, precisely regulating athletes' competitive psychology, and optimizing future competition rules.
