The Relationship Between Neutrophil/Lymphocyte Ratio Before Coronary Angiography and Coronary Collateral Development.

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
objectiveThe aim of this study was to determine the relationship between the neutrophil/lymphocyte ratio (NLR) measured before coronary angiography and coronary collateral (CC) development.
methodThis retrospective descriptive study was carried out between January 2012 and June 2013 in the cardiology outpatient clinic of a university hospital in Aydın, with 165 patients who were diagnosed with acute coronary syndrome or stable angina pectoris and who had 95% or more stenosis in at least one coronary artery according to angiography. Coronary artery stenosis was determined by Gensini scoring. The classification of CC was performed by the Rentrop method, and patients were divided into two groups: Rentrop stages 0 and 1 (poor CC filling (group 1)) and Rentrop stages 2 and 3 (good CC filling (group 2)). The data were analyzed using appropriate statistical analyses. Multivariate logistic regression was used to determine the predictors of CC level, and receiver operating characteristic (ROC) curve analysis was performed to calculate the predictive value of predictors.
resultsWhen the groups were compared, the mean age (p=0.023), Gensini score (p<0.001), smoking status (p=0.012), creatinine level (p=0.032), and aspartate aminotransferase level (p=0.032) of the patients in group 1 were significantly lower than those in group 2, while their total cholesterol (p=0.006) and low-density lipoprotein (LDL) levels (p=0.020) were higher. Neutrophils (p=0.016) and NLR (p<0.001) were significantly higher in group 2 patients. A significant positive correlation was found between CC level and neutrophils (p=0.035) and NLR (p=0.011). In regression analysis, high NLR, high Gensini score, and smoking were predictors of good CC filling. According to ROC curve analysis, the sensitivity and specificity of NLR ≥3.53 at the time of presentation to the clinic for predicting good CC filling were 37.6% and 85%, respectively.
conclusionThis study showed that NLR was significantly associated with the development of good CC filling; as NLR increased, the development of good CC filling increased in patients.
