The Role of Serum Matrix Metalloproteinase-9 as a Predictor of Delayed Cerebral Ischemia in Patients with Aneurysmal Subarachnoid Hemorrhage.

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
Delayed cerebral ischemia (DCI) is one of the major causes of a poor neurological outcome following aneurysmal subarachnoid hemorrhage (aSAH). Several biomarkers, including matrix metalloproteinase-9 (MMP-9), have been evaluated to predict the development of DCI for timely management. This prospective cohort study was done on 98 patients with aSAH presenting within 72 h of the ictus. Serum samples were collected preoperatively, 7 days after ictus, 10 days after ictus, or when the patient developed DCI, whichever was earlier. The primary objective was to correlate the serum MMP-9 levels with the development of DCI. The secondary objectives were to correlate the serum MMP-9 levels with sonographic vasospasm and the neurological outcome. There was no correlation between the serum MMP-9 levels and the development of DCI (p = 0.37). Similarly, there was no correlation between the serum MMP-9 levels and the sonographic vasospasm (0.05) nor with the modified Rankin Scale (mRS) at discharge (p = 0.27), mRS at 3 months (p = 0.22), and Glasgow Outcome Scale Extended (GOSE) at 3 months (p = 0.15). Serum MMP-9 levels do not predict the development of DCI following aSAH.
