Association between visceral fat and influenza infection in Japanese adults: A population-based cross-sectional study.
Article in PloS one, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundSeveral studies have reported that obesity is associated with influenza infection; however, the role of visceral fat remains unclear. The aim of this study was to investigate the association between visceral fat and influenza infection in community-dwelling Japanese adults.
methodsA cross-sectional study was performed using data from an annual community-based health check-up conducted from May to June in 2019. In total, 1,040 Japanese adults aged 20-89 years were enrolled in this study. Influenza infection status was determined by participants' responses to a self-administered questionnaire. The visceral fat area (VFA) was measured using a bioimpedance-type visceral fat meter. Participants were classified into four groups using the following cut-off points: VFA < 100 cm2 was set as the reference category according to the Japanese criteria, 100 ≤ VFA < 150 cm2, 150 ≤ VFA < 200 cm2, and 200 cm2 ≤ VFA. Logistic regression models were used to assess the association between VFA and influenza infection.
resultsIn total, 119 participants had influenza infections in the past year. In the multivariate adjusted model, a higher VFA was significantly associated with increased influenza infection; the adjusted odds ratio for 200 cm2 ≤ VFA was 5.03 [95% confidence interval (CI): 1.07-23.6], that for 150 ≤ VFA < 200 cm2 was 1.97 (95% CI: 0.71-5.45), and that for 100 ≤ VFA < 150 cm2 was 1.62 (95% CI: 0.84-3.12), compared with that for VFA < 100 cm2 (p for trend = 0.049). These findings were confirmed in the same cohort the following year.
conclusionsOur results suggest that visceral fat accumulation is associated with influenza infection. Large-scale prospective studies using diagnostic information for influenza infection are required to confirm this association.
