1 · What the graph read from it

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.

2 · The registry

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

Objective: The aim of this study is to examine the detection rate of chronic fatigue syndrome (CFS) in secondary school students in Shaanxi Province and its association with their physical fitness test outcomes. Methods: A survey involving the distribution of CFS questionnaires and collection of physical fitness test data was carried out among students from 25 secondary schools in Shaanxi Province. A total of 8,840 valid questionnaires and datasets were analyzed. Detection rates for CFS and chronic fatigue (CF) were determined based on screening criteria and severity levels. Gender and year group distribution variances for CFS and CF were assessed using chi-square tests, while correlation analyses were performed to evaluate the relationship between CFS and physical fitness test scores. Results: Results showed an overall CFS detection rate of 2.059% among students, with rates of 1.903% for males and 2.234% for females. There was no significant difference in CFS detection rates between genders ( Conclusion: CFS-like symptoms among secondary school students in Shaanxi Province warrant attention. The screening detection rate tended to increase with grade level and was highest among students in cram schools. Higher CFS levels were associated with poorer physical fitness achievement, particularly endurance running performance, suggesting that students with CFS-like symptoms may require additional attention in school health monitoring.
