High serum levels of TAC and early mortality in patients with spontaneous intracerebral haemorrhage.

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
objectiveOxidation contributes to secondary brain injury after spontaneous intracerebral haemorrhage (SIH). One study found lower levels of total antioxidant capacity (TAC) in the blood in patients with SIH than in healthy subjects. However, there are no data on blood TAC levels and survival in patients with SIH. Therefore, the objective of our study was to determine if an association exists between serum TAC levels and mortality in patients with SIH.
methodsWe included patients with severe supratentorial SIH. We considered severe when Glasgow Coma Scale (GCS) < 9. Patients from 6 Spanish hospitals were included in this observational and prospective study. Serum TAC levels at days 1, 4 and 8 of SIH were determined. Thirty-day mortality was our end-point study.
resultsNon-surviving patients compared with surviving patients showed higher serum TAC levels at day 1 (p < 0.001), 4 (p < 0.001) and 8 (p = 0.001). An area under the curve was found for the prediction of 30-day mortality by serum TAC levels of 0.92 (95% CI = 0.85-96%; p < 0.001). Multiple logistic regression analysis showed an association of serum TAC levels with 30-day mortality (odds ratio = 16.513; 95% CI = 2.548-107.015; p = 0.003) controlling for midline shift, glycemia, early evacuation of SIH, intracerebral haemorrhage (ICH) score, age and volume of SIH.
conclusionsThe new findings of this study are that serum TAC levels are higher in non-surviving than in surviving patients, and that they are associated with mortality and could be used to predict mortality.
