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

Monitoring and detection of organophosphate pesticides in fresh vegetables and fruits are essential due to their increased usage and harmful effects on the environment and human health. This study presents the development and evaluation of a straightforward non-enzymatic electrochemical sensor for detecting paraoxon ethyl (PoE), one of the most widely used pesticides to protect crops from pests. We have synthesized nanostructured Co-Benzene Tricarboxylic acid (BTC) metal organic framework (MOF) by a mechanochemical method at room temperature and used it directly as an electrode material to modify a glassy carbon electrode (GCE). The electrochemical detection of PoE has been carried out using a Co-BTC/GCE in a phosphate-buffered saline at pH 7.0. The modified electrode displayed a remarkable electrocatalytic response towards the reduction of PoE through the appearance of a sharp peak at - 0.68 V with high selectivity over a wide concentration range of 1-1770 µM and a low detection limit of 0.13 µM. Also, the sensor exhibited high stability and reproducibility, making it a promising tool for PoE detection in farm-fresh brinjal, grape, and strawberry. Thus, the developed sensor provides an affordable, sensitive, and dependable platform for pesticide detection and supporting environmental conservation initiatives.
