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 study introduces a novel hybrid photobioreactor system that integrates an open raceway pond (ORWP) with a Nested-bottled photobioreactor (NB-PBR) in a closed-loop configuration to enhance microalgal biomass production and CO₂ fixation. The system facilitates continuous culture circulation, improving mass transfer and mixing efficiency while ensuring optimal light exposure and CO₂ dissolution. This design resulted in a 38% increase in dry mass (3.1 g/L) and improved mass transfer and mixing times by 16.6% and 15.3%, respectively. The optimized cultivation conditions led to a 39.9% enhancement in CO₂ fixation and an 8.7% increase in photosynthetic efficiency (Fv/Fm) compared to traditional systems. The strategic movement of poorly illuminated ORWP to the NB-PBR maximized light absorption and nutrient uptake, significantly boosting overall productivity. These findings highlight the potential of hybrid photobioreactor systems in improving microalgal growth efficiency and advancing sustainable algal cultivation for commercial applications.
