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

The pathology of Alzheimer's disease (AD), the most common cause of dementia, is considered to be mainly driven by two major hallmarks (tau and amyloid beta). It is highly desirable to develop an affordable medicinal diagnostic that can be utilized worldwide for the early diagnosis of AD. Hence, p-tau231 was selected as a specific target, which appears both in AD serum and cerebrospinal fluid, for the development of a sensing platform for the diagnosis of AD. To the best of our knowledge, these are the first aptamer-mediated biosensors that rely on sensitive fluorescent and colorimetric aptasensors for the rapid monitoring of p-tau231. The nitrogen-doped carbon dot-based turn-on fluorescent aptasensor could rapidly analyze p-tau231 down to 3.64 ng/mL within 40 min, and the colorimetric Cu-enhanced-Au aptablot displayed high sensitivity at 4.71 pg/mL through a digital camera, with visibility to the naked eye down to 8 ng/mL p-tau231 within 140 min. Owing to their advantages, which include affordability, rapidity, high sensitivity, and dependence on complicated instruments, these aptamer-based biosensors offer significant potential for the early diagnosis of AD worldwide.
