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
objectiveIn this study, we investigated the relationship between serum ischemic modified albumin (IMA) levels and other hematologic features and middle cerebral artery (MCA) severe stenosis/occlusion in acute ischemic stroke (AIS) patients.
methodsThe levels of serum IMA and Albumin (ALB) of 169 AIS patients were measured, and the ratio of IMA to albumin (IMAR) and the albumin-adjusted ischemia-modified albumin index (IMA index) were calculated. Different combinations of other hematologic changes and clinical features of the patients were analyzed.
resultsThe results indicated that the levels of blood IMA and IMAR were significantly higher in the group with severe intracranial stenosis/occlusion than in the group with non-severe stenosis/ occlusion in AIS patients, while the CHE levels were significantly lower than those in the other groups. In the MCA severe stenosis/occlusion group, the levels of blood IMA and IMAR were significantly higher than that in the other vascular severe stenosis/occlusion groups, while the IMA index, ALB, and CHE were significantly lower than that in the other groups. Multiple linear regression analysis showed a significant negative correlation between IMA and albumin. A combined diagnostic ROC curve analysis showed that among AIS patients, the best combination for determining severe stenosis/occlusion of the great intracranial arteries was the admission NIHSS score + CHE (AUC = 0.783). The best combination for determining severe stenosis or occlusion of the MCA in AIS patients was IMAR combined with the admission NIHSS score and CHE (AUC = 0.827).
conclusionThe combined use of IMA, IMAR, and the IMA index has some diagnostic value in AIS caused by severe stenosis or occlusion of the MCA. IMAR, CHE, and the admission NIHSS scores are the best combinations to determine whether an AIS patient has severe stenosis or occlusion of the MCA.
