Altered Body Composition and Cytokine Production in Patients with Elevated HOMA-IR after SARS-CoV-2 Infection: A 12-Month Longitudinal Study.
Article in Biomedicines, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled 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.
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
Altered body composition and cytokine production due to SARS-CoV-2 antigens may affect homeostasis model assessment for insulin resistance (HOMA-IR) after SARS-CoV-2 infection. To elucidate this phenomenon, we conducted a longitudinal study involving 47 COVID-19 patients, who were followed up for 12 months. During recruitment, body composition and glucose indices were measured, and heparin blood samples were collected for measuring cytokine production. HOMA-IR was considered an elevated or non-elevated group based on the ratio between HOMA-IR at 12 months and 1 month of convalescence. Those with elevated HOMA-IR had a significantly higher body mass index, body fat percentage, and visceral fat rating and had a lower lean mass and lean/fat mass ratio than their counterparts. During the convalescent period, the elevated HOMA-IR group had lower TNFα, IFNγ, IL-2, IL-10, and granzyme B expression levels but had higher TNFα/IL-10, IFNγ/IL-10, IL-2/IL-10, and granzyme B/IL-10 ratios than the other group. The reduced cytokine production and pro-/anti-inflammatory imbalance in patients with elevated HOMA-IR may suggest immune cell dysfunction toward SARS-CoV-2. Patients with elevated HOMA-IR after SARS-CoV-2 infection may experience an increase in BMI and body fat percentage, leading to increased immune dysfunction and chronic inflammatory condition. A nutritional approach and promotion of physical activity may help reduce HOMA-IR and ameliorate glucose indices in these patients.
