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

Caffeine is a neurotransmitter, important to human health. This compound exists in many food products, has been added to soft drinks, pharmaceutical drugs. For many applications, a field deployable technique for quick detecting caffeine is attractive. In this paper, we report a selective optical fiber caffeine sensor using a molecularly imprinted polymer (MIP) membrane as a transducer. The membrane extracts/concentrate caffeine from sample solutions significantly improved sensor's sensitivity with a 95 times sensitivity improvement. The sensor achieved a detection limit of 2.0 μg/mL. This sensor was used to directly analyze caffeine in soft drink products without interference from sample matrix.
