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: Atherosclerotic cardiovascular disease (ASCVD) pathogenesis is closely associated with macrophages. This study sought to explore the role of phagocytosis by monocyte-derived macrophages (MDMs) in the blood in the context of coronary heart disease (CHD) and acute coronary syndromes (ACSs). Methods: This study employed a matched case-control design. Individuals with suspected CHD were recruited and allocated to a control cohort or a CHD cohort, with the latter further stratified into stable angina pectoris and ACS subgroups according to clinical diagnoses. Clinical data were collected, MDMs were isolated, and macrophage phagocytic activity was evaluated using fluorescent-labeled latex microspheres. Results: Macrophage phagocytic rates were significantly reduced in the CHD group relative to the control group, with further decreases observed in the ACS subgroup. Multivariable linear regression revealed that age, low-density lipoprotein cholesterol (LDL-C), high-sensitivity C-reactive protein (hs-CRP), and fibrinogen were independently and negatively correlated with macrophage phagocytic rates. Multivariable analyses suggested that diminished macrophage phagocytic rates were linked to an elevated risk of both CHD and ACS. Receiver operating characteristic (ROC) curve analysis identified the optimal cutoff values of macrophage phagocytic rates for predicting CHD and ACS as 62.6% and 63.4%, respectively, with the area under the curves (AUCs) measured at 0.679 and 0.669. Conclusions: Macrophage phagocytic activity is reduced in CHD patients, particularly in those with ACS. Diminished macrophage phagocytic function is linked to CHD and ACS. Macrophage phagocytosis could act as a protective biomarker in CHD and ACS, providing new insights into the pathophysiology of ASCVD.
