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
Background: Athletic performance reflects the interplay of physical, psychological, and nutritional factors. Although the individual roles of mental and dietary factors are increasingly recognized, their combined relationship with performance within a defined sports organization has rarely been examined. Objective: This cross-sectional study examined the associations of psychological factors (motivation, anxiety, mental resilience, self-confidence) and self-reported nutritional practices with self-perceived athletic performance among athletes affiliated with a sports organization in Rizhao, Shandong, China ( Methods: A descriptive, cross-sectional, analytical design was used. One hundred actively competing athletes completed self-report instruments comprising an adapted Athletic Mental Energy Scale and selected Competitive State Anxiety Inventory-2 (CSAI-2R) subscales (motivation, cognitive and somatic anxiety, mental resilience, self-confidence; 5-point Likert scaling), a nutritional practices questionnaire (pre-competition nutrition, hydration, meal regularity, supplement use), and a self-perceived performance rating (0-10). Data were analyzed in SPSS (v26) using descriptive statistics, Pearson correlation, multiple linear regression controlling for age, sport type, and competitive level, and a moderation analysis; statistical significance was set at Results: Intrinsic motivation showed the strongest positive association with self-perceived performance ( Conclusion: Within this organization, psychological factors and nutritional practices were jointly associated with self-perceived athletic performance. Integrated support combining motivational and mental-skills strategies with structured nutritional guidance appears important for athlete development, although the cross-sectional, self-report design precludes causal inference.
