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

objectiveMalondialdehyde (MDA) is an end-product formed during lipid peroxidation, due to degradation of cellular membrane phospholipids. MDA is released into extracellular space and finally into the blood; it has been used as an effective biomarker of lipid oxidation. High circulating levels of MDA have been previously described in patients with ischemic stoke than in controls, and an association between circulating MDA levels and neurological functional outcome in patients with ischemic stoke. However, an association between serum MDA levels and mortality in patients with ischemic stroke has not been previously reported, and that was the objective of this study.

methodsObservational, prospective and multicenter study performed in six Intensive Care Units. We included patients with severe malignant middle cerebral artery infarction (MMCAI) defined as Glasgow Coma Scale (GCS) lower than 9. We measured serum MDA levels in 50 patients with severe MMCAI at the time of diagnosis and in 100 healthy subjects. Mortality at 30 days was the end point of the study.

resultsWe found that patients with severe MMCAI showed higher serum MDA levels than healthy subjects (p<0.001). We found higher serum MDA levels (p<0.001) in non-surviving MMCAI patients (n=26) than in survivors (n=24). The area under the curve for prediction of 30-day mortality for serum MDA levels was 0.77 (95% CI = 0.63-0.88; p<0.001). Serum MDA levels >2.27 nmol/mL were associated with 30-day mortality (OR=7.23; 95% CI=1.84-28.73; p=0.005) controlling for GCS and age on multiple binomial logistic regression analysis.

conclusionsTo our knowledge, this is the first study showing that serum malondialdehyde levels in patients with MMCAI are associated with early mortality.
