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.
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
Nitrofurantoin (NFT) is a widely used antibiotic that requires sensitive and reliable detection due to its potential environmental and health impacts. In this study, a poly(O-cresolphthalein complexone)/electrochemically reduced graphene oxide (POC/ERGO) nanocomposite was electrochemically fabricated via one-step process and applied to a modified GCE for the electrochemical detection of nitrofurantoin. The sensing performance of the POC/ERGO-GCE was evaluated using CV and DPV. The developed sensor exhibited a wide linear detection range from 1 to 500 μM, and a low detection limit of 78.90 nM as determined by DPV. In addition, it demonstrated excellent anti-interference capability, good reproducibility and selectivity toward NFT, confirming the reliability of the proposed sensing platform. The enhanced performance is attributed to the increased electrochemically active surface area and improved electron transfer properties of the POC/ERGO-GCE. These results indicate that the proposed platform provides a reliable approach for the electrochemical detection of nitrofurantoin and offers a promising foundation for the development of antibiotic sensing systems.
