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
Background: Atherosclerosis is recognized as a potential etiological factor for hypertension. However, evidence regarding the association between the Atherogenic Index of Plasma (AIP) and hypertension in Chinese middle-aged and older adults remains limited. This study aimed to examine the association between AIP and hypertension in this population. Methods: This retrospective single-center cross-sectional study consecutively enrolled 5,254 participants undergoing routine health examinations at the Health Management Center of Union Hospital Affiliated to Huazhong University of Science and Technology (Wuhan, China) between January 2017 and December 2019. Among them, 1,799 were diagnosed with hypertension and 579 with diabetes mellitus. The association between AIP and hypertension was analyzed using logistic regression and restricted cubic splines (RCS). Stratified analyses were performed by diabetes status. Furthermore, mediation analysis was conducted to evaluate the mediating effect of body mass index (BMI) on the AIP and hypertension association. Results: In this cross-sectional study of 5,254 participants, a positive association was observed between the atherogenic index of plasma (AIP) and hypertension. After adjusting for multifactorial confounders, each 1-unit increment in AIP was associated with a 14% higher odds of hypertension (aOR = 1.14, 95% CI: 1.02-1.27). Mediation analysis confirmed that body mass index (BMI) partially mediated this association, accounting for 55.62% of the total effect ( Conclusion: These findings suggest that elevated AIP is independently and positively associated with hypertension prevalence in adults aged ≥45 years, with body mass index (BMI) mediating 55.62% of this association (
