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
In this research, male and female athletes who won gold, silverand bronze medals at the International Weightlifting Federation Senior World Championship (between 2011 and 2023); (a) analysis of successful and unsuccessful lifts in snatch and clean and jerk techniques, (b) analysis of successful and unsuccessful lifts in 3 lift attempts in both techniques and, (c) It is aimed to investigate the lifting attempts of athletes that determine their medal rankings in snatch, clean and jerk and total. In this retrospective study, data of 3144 (1603 and 1541 for male and female, respectively) individual results obtained from the lifting performances of 528 athletes (male n = 270; female n = 258) participating in the Senior World Championship (between 2011 and 2023) in snatch and clean and jerk were analyzed. In the study, the frequencies and rates of the individuals included in the study according to different variables are presented with descriptive statistics. Various Chi-square analyzes were conducted to determine differences in distribution rates between groups. The significance level in the analyzes was determined as p < .05. It was determined that the successful lifts ratios of the athletes who achieved gold, bronze, silver medals in the light weight, middle weight and heavy weight categories of the male and female groups were higher than the unsuccessful lifts ratios in both lifting techniques (excluding silver medals in clean and jerk in lightweight for men; except bronze medals in snatch in lightweight for women). It was observed that the percentage rates in the unsuccessful lifts of athletes who achieved gold medals in both snatch and clean and jerk of the male and female groups were lower than the percentage rates in the unsuccessful lifts of athletes who took part in silver and bronze medals. It was observed that there was no significant difference between the distribution rates of successful and unsuccessful lifts distribution rates according to gender in both snatch and clean and jerk of both genders. It was observed that the successful lifts rates in both the snatch and clean and jerk of the male and female groups decreased from the 1st attempt to the 3rd attempt, and the lifting rates in the unsuccessful lifts increased. It has been observed that the lift attempts that determine the medal rankings of the groups in snatch, clean and jerk and total are the 2nd attempt and 3rd attempt. The findings can provide a comprehensive perspective on the in-competition factors that contribute to World Championship success in order to directly inform coach and athlete strategies. These findings may also be valid for national or regional champions and may include other strength-based sports with a similar structure.
