1 · What the graph read from it

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.

2 · The registry

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

backgroundHemorrhagic transformation (HT) is a common complication of acute ischemic stroke (AIS), and inflammation has been found to play an important role in the occurrence of HT. We aimed to investigate the impact of lymphocyte-to-monocyte ratio (LMR), a maker of inflammatory status, on HT in patients with AIS.

methodsConsecutive AIS patients within 7 days from stroke onset were enrolled between January 2016 and October 2017. LMR was calculated according to lymphocyte and monocyte counts obtained within 24 h on admission. Patients were categorized into three groups according to LMR tertiles. HT was detected by follow-up computed tomography (CT) or magnetic resonance imaging (MRI) during hospitalization. The multivariate logistic analysis was used to evaluate the independent relationship between LMR and HT.

resultsA total of 1005 patients were finally included. HT was observed in 99 (9.9%) patients, with 51 (5.1%) hemorrhagic infarction (HI) and 48 (4.8%) parenchymal hematoma (PH). After adjustment for potential confounders, the odds ratio (OR) of HT was 0.523 (95% confidence interval [CI] 0.293-0.936, P = 0.029) for the highest LMR tertile compared with the lowest tertile. Multiple-adjusted spline regression model showed a nonlinear approximately L-shaped relationship between LMR levels and HT (P for nonlinear trend = 0.030). There was no significant association of baseline LMR with PH (OR 0.562, 95% CI 0.249-1.268, P = 0.165).

conclusionLower LMR was independently related to higher risk of HT in patients with AIS. Admission LMR may be used as one of the predictors for HT. Further prospective multicenter studies are needed to validate our findings.
