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
To maximize photovoltaic (PV) energy extraction, this study proposes a novel hybrid maximum power point tracking (MPPT) method that combines artificial neural networks (ANNs) with particle swarm optimization (PSO). The ANN-PSO controller is integrated within a PV-battery microgrid system and enables efficient tracking of the maximum power output while minimizing oscillations. The MPPT unit operates alongside a droop-controlled inverter to coordinate the power flow between the PV array and battery energy storage system (BESS), supporting dynamic transitions between grid-connected and islanded modes. The controller monitors the current and voltage at the point of common coupling (PCC) to ensure reliable power delivery. By enhancing the accuracy of irradiance estimations, the ANN-PSO approach improves tracking responsiveness and overall system efficiency. The proposed strategy is benchmarked against traditional and intelligent MPPT techniques, including Perturb & Observe, ANFIS-PSO, and PSO-SMC, under varying irradiance and load conditions. The performance is validated through detailed MATLAB/Simulink simulations. The results demonstrate superior tracking performance and faster, more stable microgrid operation, highlighting the controller's potential for efficient renewable energy integration. This work supports the advancement of intelligent, autonomous energy systems and contributes to the development of resilient, grid-interactive solar microgrids. This research supports SDG 7: Affordable and Clean Energy by enhancing the efficiency and integration of solar energy systems, and it aligns with SDG 9: Industry, Innovation, and Infrastructure through the development of advanced control strategies for smart power grids.
