An enhanced Draco lizard optimizer for accurate parameter extraction of proton exchange membrane fuel cells.
Article in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Accurate parameter extraction is crucial for the modelling of proton exchange membrane (PEM) fuel cells, which involves complex, non-linear, and multivariate relationships essential for simulation, design, and fault diagnostics. This paper proposes a Modified version of the Draco Lizard Optimizer (MDLO) technique to precisely extract important PEM fuel cell parameters. This hybridization aims to increase optimization efficiency by striking a balance between exploration and exploitation. The efficacy of MDLO is supported by extensive simulations that use three commercially available PEM fuel cell systems to compare its performance to that of the conventional DLO and new metaheuristic optimization approaches, which are Driving Training-Based Optimization (DTBO), Moss Growth Optimization, and Skill Optimization Algorithm (SOA). Best fitness, average fitness, worst fitness, standard deviation, convergence speed, and multiple-comparison test are among the performance indicators that are applied and measured during the course of 55 runs. According to the findings, MDLO provides the best Sum of Squared Errors (SSE) value, greater accuracy, dependability, speed of convergence, and a strong fit for the estimated primary parameters. The runs' low and consistent SSE values-0.331348 for the 250 W, 1.1698 [Formula: see text] 10
