Gender Differences in the Correlations Between Immune Cells and Organ Damage Indexes of Acute Myocardial Infarction Patients.

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: There are clear gender differences in the pathological process and outcome in acute myocardial infarction (AMI) patients but inflammatory responses remain clarified. Here, we aimed to analyse the correlations between inflammatory cells and organ injury parameters in AMI patients and compared between male and female groups. Methods: A total of 603 AMI patients who underwent percutaneous coronary intervention (PCI) within 24 hours of the onset were analysed retrospectively. Basic information and hematological parameters detected 6 hours before the PCI were collected, neutrophil-to-lymphocyte ratio (NLR) and monocyte-to-lymphocyte ratio (MLR) were calculated. Renal, liver function indicators, and myocardial enzymes were measured. Left ventricular ejection fraction (EF) and fractional shortening (FS) on days 5-7 after PCI were obtained. Western blot was performed to detect iNOS, eNOS and nNOS expression in H9C2 rat cardiomyocytes treated with IL-6 with and without estrogen and testosterone. Results: WBC, NEU, MON, MLR, CK, ALT and CREA of male patients were significantly higher than females, but FS was lower in females. NEU, MON and MLR were positively correlated with CK, CK-MB, AST, and ALT in males, whereas LYM were correlated with these parameters in female. NEU and NLR were inversely correlated with EF or FS only in female. Estrogen and testosterone reduced IL-6-induced iNOS protein expression in H9C2 cardiomyocytes, estrogen enhanced IL-6-induced nNOS protein expression. Conclusion: NEU, MON, MLR in male AMI patients, and LYM in female patients were associated with organ injury parameters. Estrogen regulation of nitric oxide pathway may mediate the protective effects in female.
