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
There are several difficulties to overcome when integrating electric vehicles (EVs) into power distribution networks, especially when it comes to preserving power quality (PQ) because of the harmonic distortion produced throughout battery charging. These issues are not sufficiently addressed by conventional charging algorithms like Constant Current Constant Voltage (CCCV), which frequently leads to higher Total Harmonic Distortion (THD), decreased system efficiency, and generally insufficient performance PQ. The Constant Power Constant Voltage (CPCV) charging algorithm, which is a revolutionary approach to addressing these issues, dynamically modifies the charging power according to the battery's state of charge (SoC). Compared to conventional techniques, this creative technology efficiently controls harmonic emissions and enhances power quality. Three distinct EV models-the Tesla Model 3, the BYD ATTO 3, and the Kia EV3 Long Range-were used in simulations to assess the algorithm's performance. The findings show that the CPCV algorithm works noticeably better than the CCCV method with respect to of lowering harmonic distortion; for the 3rd, 5th, 7th harmonics, THD values were lowered to as low as 0.41%. Furthermore, comparing to the greater loss seen in CCCV (3.85 kWh to 5.89 kWh), the CPCV algorithm also demonstrated significant decreases in energy losses, ranging from 2.72 kWh to 3.51 kWh. Furthermore, the CPCV method boosted efficiency by guaranteeing a power factor that was almost constant throughout all charging conditions. These results demonstrate the CPCV algorithm's efficacy in improving power quality, maximizing energy use, and facilitating the smooth integration of EVs into contemporary distribution systems. In order to meet the increasing demand for EV charging infrastructure and guarantee an additional dependable and sustainable power system, CPCV offers an attractive option by reducing harmonic distortion and increasing general charging efficiency.
