Association between influenza infection and cardiovascular diseases: A systematic review and meta-analysis.
Review in JRSM cardiovascular disease. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Objectives: Influenza infection may increase the risk of cardiovascular diseases (CVDs), but the extent of this link is uncertain. This systematic review and meta-analysis aimed to quantify the association between influenza infection and CVDs. Methods: We conducted a comprehensive search of major databases from inception to 2024, identifying studies that investigated the association between influenza infection and CVDs. Eligible studies included cohort, case-control, and randomized controlled trials reporting on cardiovascular outcomes (acute CVDs) following influenza infection or risk of influenza infection in CVD patients (chronic CVDs). Data were extracted and pooled using random-effects models, and heterogeneity was assessed using the Results: A total of 11 studies (15 datasets) involving 7327 participants were included in the meta-analysis. Overall, influenza infection was significantly associated with CVDs based on 10 datasets (odds ratio (OR) = 1.76, 95% confidence interval (CI): 1.02-3.03). However, the analysis of the five datasets indicated no significant association between pre-existing CVDs and an increased risk of influenza infection (OR = 0.91, 95% CI: 0.80-1.03). Subgroup analyses and meta-regression highlighted that study quality and design could significantly influence the risk of developing CVDs among patients with influenza. Conclusions: This meta-analysis provides quantitative evidence that influenza infection could be a potential risk factor for subsequent cardiovascular events. These findings emphasize the need for preventive measures, including vaccination, especially in high-risk populations. Further research is needed to explore the underlying mechanisms and impact of influenza on cardiovascular outcomes.
