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 development of fluorescent sensors with high sensitivity and fast response times is attracting the interest of more and more researchers. Herein, dual-emission ratiometric molecularly imprinted fluorescent encoded microspheres were fabricated and applied for the fast detection of norfloxacin. Core-shell-structured imprinted polymers with ZIF-8 as the supporting core were obtained first and two quantum dots with green and red emission provided the fluorescent signal. The introduction of the optical encoding technique greatly simplified the preparation process. After the addition of NOR, the green intensity at 525 nm remained constant and the fluorescent intensity at 625 nm decreased significantly because of the inner filter effect. Under the optimum detection conditions, a good linear correlation ranged from 5 μg L
