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

A fluorinated covalent organic framework composed of 2,3,5,6-tetrafluoroterephthaldehyde (TFA) and 1,3,5-tri(4-aminophenyl)benzene (TAPB) is proposed for electrochromatographic separation. TFA-TAPB is for the first time regarded as the stationary phase of capillary electrochromatography. The TFA-TAPB-coated capillary columns exhibited satisfactory separation (resolution values > 1.5) and good reproducibility towards fluoroquinolones. The intraday relative standard deviations (RSDs) of retention time and peak areas were 0.54-0.68% and 1.69-2.82%, respectively. The interday RSDs of retention time and peak areas were less than 1.79% and 2.30%, respectively. The column-to-column RSDs of retention time and peak areas were 0.22-0.73% and 0.74-1.86%, respectively. And, the inter-batch RSDs of retention time and peak areas were less than 0.39% and 1.67%, respectively. Moreover, the possible separation mechanism was discussed, and it was found that the π-π stacking effect, hydrophobic interaction, hydrogen bonding, and fluorous interactions were the main factors. Overall, these results demonstrated that TFA-TAPB has high prospect for CEC separation.
