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 paper presents the Modular Open-Source Stirred Tank Reactor (MOSTR), an IoT-enabled system developed for teaching chemical engineering principles such as residence time distribution, flow balancing and process instrumentation within higher education laboratories. Developed as a low-cost and pedagogically informed alternative to commercial units, the MOSTR's modular design allows for the simultaneous deployment of multiple rigs to enhance student engagement and inclusivity in practical learning at scale. The reactor integrates an M5Stack-based control unit with flow, temperature, and conductivity sensing, supported by real-time data streaming via Wi-Fi and Virtual Machine (VM) server infrastructure. The design emphasizes reproducibility through accessible fabrication techniques, such as 3D printing and prioritises both maintainability and pedagogical alignment. Characterisation tests demonstrate that the system is highly sensitive to mixing variations and modular configurations, which highlights its versatility for diverse educational experiments. To support global adoption and adaptation in open engineering education, all design files, software, and documentation are shared under CC BY 4.0 and MIT licenses.
