1 · What the graph read from it

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.

2 · The registry

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

backgroundAlzheimer's disease is one of the most common neurodegenerative and dementia disorders in people between the ages of 30 and 65. When symptoms appear in this age group, the disease is referred to as early-onset Alzheimer's disease (EOAD). Unfortunately, the symptoms are progressive and no current treatments are effective.

methodsIn this research, 13 patients, aged 37 to 65 years with symptoms of early-onset Alzheimer's disease, were studied. First, patient lymphocytes were isolated and cultured in RPMI 1640 medium using a special micronucleus (MN) culture method. Next, the lymphocytes were harvested and prepared on slides. The slides were then examined by fluorescent microscopy using a unique FISH protocol specific for MNs. The patients were divided into groups aged 30-39, 40-49, and 50-65.

resultsWe found that 19.76% of the MNs from our EOAD patients originated in chromosome 21. Micronuclei originated in chromosome 21 in 21.20 and 16.52% of patients without and with family histories of Alzheimer's, respectively. This difference was not significant. Also, the percentage of micronuclei originating in chromosome 21 was not dependent on the patient age at the time of the study, or symptom onset age or duration.

conclusionThis study shows that the rate of micronuclei with the origin of chromosome 21 is high in these patients. However, the micronucleus increased has no significant relationship with age and duration of disease or family history of it.
