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
As critical load-bearing components of high-speed trains, bogies endure multidirectional alternating loads during long-term operation, making their dynamic strain characteristics and structural integrity pivotal to operational safety. Therefore, real-time dynamic strain monitoring of bogies is essential for predicting and preventing high-speed train accidents. Compared to traditional Non-Destructive Testing and Evaluation (NDT&E) methods, Radio Frequency Identification (RFID) sensors are more suitable for Structural Health Monitoring (SHM) due to their wireless capabilities and cost-effectiveness. Here we propose a wireless real-time monitoring system that utilizes integrated RFID tags with microcontrollers and sensor modules for real-time dynamic strain monitoring of Einel-rad-Einelfahrwerk (EEF) bogies. The microcontroller converts analog signals into digital, enhancing environmental interference resistance. The RFID tags wirelessly transmit digital signals to readers and host computers. To verify accuracy and real-time dynamic strain detection capabilities of designed system, experiments were conducted in laboratory settings and on-site with high-speed train bogies. Experimental results validate the system's 200 Hz dynamic strain detection capability with a 70 cm operational range. Laboratory calibrations within 600-1400 με exhibited absolute errors <19.39 με (2.07%). On-site tests on bogies revealed absolute errors of 5.08 με (7.50%) for axle strain and 7.59 με (7.66%) for wheel hub lateral strain under operational conditions.
