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
Microalgae cultivation is a field with significant potential across various industries, such as pharmaceuticals, food, cosmetics, and energy. Aiming to optimize the geometric parameters of a paddlewheel agitation system through computational fluid dynamics (CFD) and experimental validation, an investigation was conducted involving different rotation speeds, blade pitch angles, and the number of blades on a paddlewheel within a microalgae cultivation tank. The results revealed paddlewheels with 90° inclined blades exhibited higher average flow velocities. Regarding the vertical mixing index, the 8-blade paddlewheels demonstrated inferior performance compared to systems with four and six blades. A pitch angle of 60° minimized power consumption. The optimal configuration found was a 60°-angled 4-blade paddlewheel, operating at a rotation speed of 19 rpm, yielding the highest mixing performance index value at 46.12 W
