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
The basic contemplate of this work is to enhance the power and frequency variances of power system. The integration of wind and solar energy along with pumped hydrogen energy storage (PHES) may enhance the challenge to maintain the stability of the system. The design of smart and knowledgeable controller is immensely obligatory for stability of hybrid power system. In this work, intelligent fuzzy fractional order proportional integral derivative cascaded with 1 + fractional order proportional integral (FFOPID (1 + FOPI)) is designed for frequency regulation of power system. The immensely influential parameters of proposed FFOPID (1 + FOPI) controller are decided by forensic-based investigation (FBI) and quasi oppositional-based FBI (QOFBI) algorithms. The integration of QOFBI and FFOPID (1 + FOPI) is tested in four different power system environments over other controllers. The supremacy of proposed QOFBI based FFOPID (1 + FOPI) controller is confirmed through simulation result analysis by considering some statistical errors such as undershoot, overshoot, settling time and integral of time-weighted absolute error. The improvement of proposed controller over other controllers is quietly detectable in terms of frequency and tie-line power deviations. These results demonstrate that intelligent optimization in conjunction with fuzzy logic based fractional-order control can effectively increase system robustness in transient scenarios. The results of this research demonstrate that PHES is an appropriate choice for preserving frequency stability throughout the development of smart and renewable-dominated power grids when combined with RESs.
