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
This article introduces a novel ultra-high voltage gain DC-DC converter with a low component count, designed for renewable energy applications. In the presented topology, a three-winding coupled-inductor (TWCI) and a switched-capacitor network are embedded within a classic quadratic boost converter. This arrangement yields high voltage gain, ensures continuous low-ripple input current, and preserves a common ground between the source and the load. Due to its trans-inverse feature, the circuit achieves ultra-high voltage gain even with a very low turns ratio in the TWCI. The topology also features current sharing between the TWCI and the main power switch, which significantly reduces power losses in the main power switch and coupled-inductor device. To limit voltage stresses on the active switches, the circuit integrates two passive regenerative clamp circuits, with the switches themselves operated using simultaneous switching patterns. The paper provides detailed steady-state analysis, power loss calculations, comparative evaluation, and design considerations. Finally, a laboratory prototype rated at 200 W has been implemented to verify the theoretical analysis, achieving a very high voltage conversion from 20 V input to 400 V output.
