Neuropathology of 30 deceased patients with COVID-19: a case series in Tehran, Iran.
Article in Annals of medicine and surgery (2012), 2023. 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
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can affect the nervous system and result in neurological symptoms. The most common feature of central nervous system involvement is hypoxia and congestion. This study aimed to evaluate the histopathology of cerebral tissue in deceased patients with coronavirus disease 2019 (COVID-19). Methods: In a case series study, we took cerebral samples of 30 deceased patients with COVID-19 through supraorbital bone from January to May 2021. The samples were fixed in a formalin solution, stained with haematoxylin-eosin dyes and studied by two expert pathologists. The Ethics Committee of AJA University of Medical Sciences approved this study with code IR.AJAUMS.REC.1399.030. Results: The mean age of the patients was 73.8 years, and the most common underlying disease was hypertension. Cerebral tissue samples showed hypoxic-ischaemic changes in 28 (93.3%), microhaemorrhage in six (20%), lymphocytic infiltration in five (16.7%) and thrombosis in three samples (10%). Conclusion: Hypoxic-ischaemic change was the most common neuropathology in our patient. Our study showed that many patients with severe COVID-19 may develop central nervous system involvement.
