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

Despite extensive studies regarding tau phosphorylation progression in both human Alzheimer's disease cases and animal models, the molecular and structural changes responsible for neurofibrillary tangle development are still not well understood. Here, by using the antibodies AT100 (recognizes tau protein phosphorylated at Thr212 and Ser214 in the proline-rich region) and pS396 (recognizes tau protein phosphorylated at serine residue 396 in the C-terminal region), we examined phospho-tau immunostaining in neurons from the hippocampal CA1 region of 21 human cases with tau pathology ranging from Braak stage I to VI. Our results indicate that the AT100/pS396 ratio decreases in CA1 in accordance with the severity of the disease, along with its colocalization. We therefore propose the AT100/pS396 ratio as a new tool to analyze the tau pathology progression. Our findings also suggest a conformational modification in tau protein that may cause the disappearance of the AT100 epitope in the late stages of tau pathology, which may play a role in the toxic tangle aggregation. Thus, this study provides new insights underlying the stages for the formation of neurofibrillary tangles in Alzheimer's disease.
