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

Copper ions (Cu²⁺) are essential trace elements that play a vital role in maintaining physiological activities, while their homeostasis imbalance is associated with the pathogenesis of various diseases. Therefore, developing a highly selective and sensitive detection method for copper ions (Cu²⁺) is of significant importance. This study successfully synthesized a novel fluorescent probe, tetraphenylimidazole derivative (TPHB), for the specific recognition of copper ions (Cu²⁺). It exhibits excellent optical properties, including fluorescence quenching upon Cu²⁺ binding. The detection limit reaches as low as 0.047 µM, with a binding constant (K) of 3.56 × 10⁴ M
