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
introductionObesity has arisen as a prominent risk factor for COVID-19 severity and long COVID, potentially owed in part to the obesity-induced proinflammatory state. This study aimed to examine relationships among circulating inflammatory biomarkers and body mass index in nonhospitalized adults recently diagnosed with COVID-19.
methodsThis analysis included participants who completed a randomized placebo-controlled trial conducted in October 2020-March 2021. Participants (19-53 years) were unvaccinated and enrolled following COVID-19 diagnosis as allowed by CDC return-to-work guidance. Anthropometrics and biomarkers were assessed at study baseline and week four. We examined the associations between body mass index (BMI) and inflammatory biomarkers via multiple regression models.
resultsAt study baseline (i.e., the point of enrollment following COVID-19 diagnosis) across all participants (N = 60), a higher BMI was associated with elevations in several inflammatory biomarkers including IL-6 (β = 7.63, 95% CI = 3.54, 11.89, p = 0.0004), ferritin (β = 6.31, 95% CI = 1.97, 10.83, p = 0.0047), high sensitivity C-reactive protein (β = 13.1, 95% CI = 8.03, 18.42, p = < 0.0001), tumor necrosis factor-α (β = 3.23, 95% CI = 0.91, 5.60, p = 0.0069), IL-12p40 (β = 3.69, 95% CI = 0.93, 6.52, p = 0.0094), IL-13 (β = 5.11, 95% CI = 1.00, 9.40, p = 0.0154), and IL-1Ra (β = 7.57, 95% CI = 3.61, 11.70, p = 0.0003). In control group participants (n = 30) after 4 weeks, a higher BMI was associated with elevations in IL-4 (β = 17.8, 95% CI = 0.84, 37.6, p = 0.0397) and sP-selectin (β = 1.16, 95% CI = 0.22, 2.11, p = 0.0182), controlling for baseline and covariates.
conclusionsHere, BMI was positively associated with circulating biomarkers of platelet activation and inflammation in adults recently diagnosed with COVID-19 after 4 weeks. The shift in post-acute COVID-19 inflammatory biomarkers associated with an increasing BMI noted here shares similarities to biomarkers of LC reported in the literature.
