Association of Anaemia With Higher Mortality and Disability After Subarachnoid Haemorrhage: A Single-Centre Cohort Study.
Article in Cureus, 2025. 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
backgroundCritical care management in subarachnoid haemorrhage (SAH) aims to facilitate neuroprotection and prevent secondary neurological insults. Anaemia after SAH leads to reduced cerebral oxygen delivery and poor outcomes. This study aimed to investigate the association between anaemia and mortality and morbidity outcomes in patients with SAH in tertiary centres, as well as evaluate the impact of blood transfusions on outcomes in anaemic SAH patients. Methods: We performed a retrospective study of 987 patients with SAH at a tertiary neurocritical care centre between September 2016 and September 2018. Data were collected on baseline characteristics, World Federation of Neurosurgical Societies SAH grade, secondary insults such as anaemia and hydrocephalus, and units of blood transfused. The primary outcome was to investigate the correlation between anaemia and 28-day Modified Rankin Scale (MRS) score. Secondary outcomes were delayed neurological deficits, length of stay and death in the intensive care unit (ICU). Anaemia was defined as haemoglobin (Hb) ≤ 95 g/L, and severe anaemia as Hb≤80 g/L. Results: Of the patients, 28.7% had anaemia and 12% had severe anaemia. Anaemia after SAH was associated with an increased risk of death or severe disability (p<0.001), worse survival outcomes (p<0.001) and increased length of stay in ICU (p<0.001).
conclusionsAnaemia after SAH is associated with a significant increase in mortality and morbidity and should be monitored closely and corrected.
