Post-COVID-19 syndrome and low-grade inflammation: exploring gender and occupational inequalities in a retrospective cohort study.
Article in International health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundTo investigate the association between post-coronavirus disease 2019 (COVID-19) syndrome (PCS) and chronic low-grade inflammation (LGI) in blood cells in 4108 mild COVID-19 patients.
methodsThe data were collected within 12-24 weeks before and 24 weeks after COVID-19 infection. The χ2 test was utilized to analyse the differences between two groups. The relationship between PCS symptoms and inflammatory cells was analysed by logistic regression analysis.
resultsThe most common PCS symptom was cough, reported as 'occasionally' by 33.47% and 'frequently' by 5.92%. Women exhibited more severe symptoms than men. Among healthcare workers, palpitations were more pronounced (0.76% versus 0.35%), while the prevalence of other PCS symptoms was lower compared with non-healthcare workers. After adjusting for confounding factors, women showed a higher risk of five types of PCS, and healthcare workers had a greater risk of fatigue and dizziness compared with the non-healthcare worker. Fatigue was associated with lymphocytes, monocytes and the neutrophil:lymphocyte ratio (NLR). Cough correlated with high-sensitivity C-reactive protein (hs-CRP), NLR and the platelet:lymphocyte ratio (PLR). Dizziness was linked to hs-CRP, NLR and PLR. Palpitations correlated with hs-CRP.
conclusionsOur findings suggest that PCS symptoms may be associated with LGI in peripheral blood cells, gender and occupational inequalities, warranting further investigation.
