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

Background: Long COVID following SARS-CoV-2 infection is a public health concern. Brain fog, a symptom of long COVID, has an impact on patients' daily lives and health. However, studies on the effects of COVID on college students are limited. Methods: This cross-sectional study included students from two tertiary institutions in Taizhou, China. Data were collected using WeChat-based electronic questionnaires on the Wen-Juan-Xing survey platform from July 20, 2023 to August 7, 2023. Chi-square analyses and binary logistic regression were used to evaluate the factors contributing to brain fog. Results: A total of 1,071 students participated in the survey. Of these 1,071 students, 13.7% (147/1,071) reported experiencing long COVID, of whom 27.2% (40/147) reported symptoms of brain fog. Significant associations with brain fog were observed for the following factors: age (> 20 Conclusions: This study highlights the significant prevalence of long COVID brain fog among college students and identifies key associated factors, underscoring the need for specific, focused interventions and support for affected individuals.
