Relationship Between D-Dimer Levels and Neutrophil-to-Lymphocyte Ratio (NLR) in Preeclamptic Pregnant Women with COVID-19: A Cohort Study.

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 Preeclampsia involves an inflammatory response and vascular endothelial dysfunction. In COVID-19, there is also tissue damage and an inflammatory response that stimulates the formation of D-dimers and an increase in the neutrophil-to-lymphocyte ratio (NLR). These 2 parameters have become laboratory tests carried out both in preeclampsia and COVID-19. This study aimed to determine the relationship between D-dimer levels and NLR in patients with both COVID-19 and preeclampsia. MATERIAL AND METHODS This was an observational analytic study with a retrospective approach. The subjects were pregnant women with gestational age >20 weeks diagnosed with severe preeclampsia and had D-dimer and neutrophil-to-lymphocyte ratio (NLR) laboratory results at Hasan Sadikin Hospital Bandung during the period April 2020 to July 2021. We enrolled 31 COVID-19 patients with preeclampsia and 113 COVID-19 patients without preeclampsia. RESULTS The mean level of D-dimer in COVID-19 patients with preeclampsia was 3.66±3.15 and in those with COVID-19 without preeclampsia it was 3.03±3.15 (P<0.05). The mean NLR value in COVID-19 patients with preeclampsia was 7.22±4.30 and in COVID-19 patients without preeclampsia it was 5.47±2.20 (p<0.05). In the Spearman correlation test, the correlation coefficient was 0.159. Area under curve (AUC) D-dimer level was 64.9% (p<0.05) and NLR was 61.7% (p<0.05). CONCLUSIONS There was a significant difference (P<0.05) in D-dimer and NLR between COVID-19 patients with preeclampsia and those without preeclampsia. There was also a weak positive relationship between D-dimer and NLR levels in COVID-19 patients with preeclampsia, which means that the higher the D-dimer level, the higher the NLR value in COVID-19 patients with preeclampsia.
