Effects of anemia on short-term prognosis and imaging features of patients with acute ischemic stroke: preliminary findings.
Article in BMC neurology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundThis study aimed to investigate the relationship between anemia, stroke severity, short-term prognosis, and imaging features of infarction.
methodsThe clinical features and imaging data of patients with anemia and acute ischemic stroke were retrospectively analyzed. All patients were divided into anemia and non-anemia groups, and according to the degree of anemia, they were divided into mild anemia group and moderate and severe anemia group. Stroke severity, short-term prognosis, and infarct lesion characteristics were compared between all groups.
resultsAmong the 238 AIS patients, we found that the prevalence of anemia was 25.6%. There was significant correlation between the severity of anemia and NIHSS at admission (P = 0.01); The severity of anemia affected 90-day mRS (P = 0.01), and increased the length of hospital (P < 0.01). In the moderate and severe anemia group, there were 16 cases of watershed infarction, 15 of cerebral infarction, and 14 of corona radiata and centrum semiovale infarction. Multiple infarcts were more significantly common in the moderate and severe anemia group (P < 0.01).
conclusionThe degree of anemia correlated with the severity of acute ischemic stroke. Furthermore, the severity of anemia was closely related to patient prognosis. The infarct sites of moderate and severe anemia were mostly in the cerebral lobe, corona radiata, and centrum semiovale, and the watershed area was prone to infarction with multiple infarction lesions, which may be related to tissue hypoperfusion.
