1 · What the graph read from 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.

2 · The registry

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

Objective: Carotid atherosclerosis (CAS) is a significant factor contributing to cardiovascular events and poses a major public health concern. There are still many controversies about the association between serum bilirubin and CAS. This study aims to provide a systematic review and meta-analysis to examine the association between serum bilirubin levels and carotid atherosclerosis. Methods: An electronic literature search was performed using PubMed, Web of Science and Embase up to December 2023. Articles were screened based on predefined inclusion criteria and assessed for risk of bias and quality of evidence utilizing the Newcastle-Ottawa Scale and GRADE tool. Pooled mean differences were calculated using a random effects model. Subgroup and meta-regression analyses were performed to identify potential sources of heterogeneity. Results: Nine studies involving 7,023 participants were included in this meta-analysis. The results indicated that patients with carotid atherosclerosis exhibited lower levels of total bilirubin compared to those without (SMD -3.42, 95% CI [-5.18, -1.67]), with a statistically significant difference (z=-3.819, Conclusion: Lower serum bilirubin levels are associated with an increased risk of carotid atherosclerosis. This meta-analysis offers new insights into the development of diagnostic biomarkers and therapeutic targets. Further prospective cohort studies are necessary to validate our conclusions.
