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
Background: Accurate diagnosis of sCJD remains challenging in developing countries such as Vietnam, as clinical and research efforts focus on treatable diseases. Several cases of sCJD have been diagnosed in Vietnam but data from formal analyses are lacking. This is the first systematic analysis of patients with sCJD in Vietnam. Methods: This was a systematic retrospective review of medical records from patients with probable sCJD (N = 31) seen between April 2021 to April 2024 at four tertiary care centers. Clinical, laboratory, neuroimaging, and EEG findings were included in the analysis. Results: Data from 16 men and 15 women with sCJD were analyzed. The average age of onset was 63.4 years (range 50-83 years). Twenty-one of the patients had died after a mean survival of 7.6 months (range 3-20 months). All patients initially presented with rapidly progressive dementia. Other associated symptoms included myoclonus (77 %), extrapyramidal symptoms (80 %), pyramidal symptoms (58 %), akinetic mutism (55 %), visual disturbance (45 %), and cerebellar ataxia (32 %). Neuroimaging revealed abnormal fluidattenuated inversion recovery (FLAIR) and diffusion-weighted imaging (DWI) sequences in 28/31 patients. EEG revealed periodic sharp wave complexes (PSWCs) in 26/31 patients. Only 12 patients had been tested for 14-3-3 protein in CSF and all were positive. Conclusions: Clinical, neuroimaging, laboratory, and EEG features are consistent with global findings.
