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
With the rapid development of the global plastic industry, microplastic pollution has become an increasingly serious environmental concern. However, standardized technologies for convenient, accurate, and real-time microplastic detection are limited. To address this challenge, a microwave resonant sensor with a complete microplastic detection system equipped with a Bluetooth module for remote real-time monitoring of microplastic concentrations was developed. Microplastic concentrations were measured in deionized water containing polyvinyl chloride powder (particle size: 6.5 ± 1 μm), simulated artificial seawater, and real seawater samples. The integration of the microfluidic system mitigated the interference caused by the complex seawater matrix, thereby ensuring stable and reliable microwave-based detection of microplastic concentrations. The system demonstrated high repeatability for predicting the concentration of microplastics in seawater samples. The proposed method demonstrated a recognition rate of over 96% with a tolerance of ±0.01 mg/mL, while maintaining a minimum detection limit of 48.72 ng/mL. To improve the prediction accuracy, a convolutional neural network algorithm was employed to predict microplastic concentrations based on the test results, with the predicted and actual concentrations being highly consistent. Finally, a compact and portable seawater microplastic monitoring system was developed by integrating the microwave sensor with Bluetooth and embedded systems, enabling real-time microplastic concentration monitoring in marine environments.
