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

Residual small amounts of harmful substances in food or medicine are potential threats to human health. In this work, amino-functionalized UiO-66 was firstly prepared, namely UiO-66-(a), then it was further treated with phosgene to obtain UiO-66-(b) with abundant carboxyl groups. By doping, the fluorescent Rhodamine 6G (R6G) was incorporated into the structures of the two functional UiO-66s to obtain R6G@UiO-66-(a) and R6G@UiO-66-(b), respectively. These two materials can both emit fluorescence based on UiO-66s and R6G, therefore, were employed as fluorescent probes to construct two ratiometric fluorescent sensors to detect formaldehyde and amine compounds, respectively. Based on the aldehyde-amine condensation reaction between -NH
