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
This paper introduces the current status of Seoul National University Hospital Dementia Brain Bank (SNUH-DBB), focusing on the concordance rate between clinical diagnoses and postmortem neuropathological diagnoses. We detail SNUH-DBB operations, including protocols for specimen handling, induced pluripotent stem cells (iPSC) and cerebral organoids establishment from postmortem dural fibroblasts, and adult neural progenitor cell cultures. We assessed clinical-neuropathological diagnostic concordance rate. Between 2015 and September 2024, 162 brain specimens were collected via brain donation and autopsy. The median donor age was 73 years (1-94) with a male-to -female ratio of 2:1. The median postmortem interval was 9.5 hours (range: 2.5-65). Common neuropathological diagnoses included pure Lewy body disease (10.6%), Lewy body disease (LBD) with other brain diseases (10.6%), pure Alzheimer's disease-neuropathological change (ADNC) (6.0%), ADNC with other brain diseases (10.7%), vascular brain injury (15.2%), and primary age-related tauopathy (7.3%). APOE genotype distribution was following: ε3/ε3: 62.3%, ε2/ε3: 9.6%, ε2/ε4: 3.4%, ε3/ε4: 24.0%, and ε4/ε4: 0.7%. Concordance rates between pathological and clinical diagnoses were: ADNC/AD at 42.4%; LBD at 59.0%; PSP at 100%; ALS at 85.7%; Huntington's disease 100%. The varying concordance rates across different diseases emphasize the need for improved diagnostic criteria and biomarkers, particularly for AD and LBD. Tissues have been distributed to over 40 national studies. SNUH-DBB provides high-quality brain tissues and cell models for neuroscience research, operating under standardized procedures and international guidelines. It supports translational research in dementia and neurodegenerative diseases, potentially advancing diagnostic and therapeutic strategies.
