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: This 1-year cohort study aimed to track long COVID prevalence, identify associated risk factors, and assess its association with hospitalization. Methods: The GINA-COVID cohort study included 2698 COVID-19 patients from Spain, who reported persistent symptoms spontaneously mentioned in an open questionnaire one year after infection. We recorded symptom onset, duration, and recovery rates at 12 months. Hospitalization data were collected from the Catalan Health System. We performed descriptive statistics and logistic regression models stratified by sex to identify factors associated with long COVID, using multiple imputation for missing values and model selection via stepwise regression based on the Akaike Information Criterion. Results: Significant sex differences appeared, with females showing a two-fold higher risk of developing long COVID compared to males (OR=1.95; 95% CI, 1.68-2.29). Females reported higher prevalence and a greater number of persistent symptoms, with fatigue being the most common in both sexes (36% in females, 26% in males at 3 months). The recovery rate at 12 months was lower in females (23% vs. 34%, p<0.001). Hypertension emerged as the most significant protective factor for long COVID in females (OR=0.64; 95% CI, 0.48-0.84), whereas COVID-19 severity was the most influential risk factor in males (OR=2.34; 95% CI, 1.79-3.08). Despite these differences, the trajectory of persistent symptoms over time was similar between the sexes. Importantly, long COVID did not increase hospital admissions. Conclusion: Findings underscore the importance of sex-specific approaches in managing long COVID and suggest further investigation into hypertension's protective role in females and disease severity's impact in males.
