1 · What the graph read from it

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.

2 · The registry

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 rising demand for spirulina (Limnospira spp.) highlights the need for affordable cultivation methods and practical biomass monitoring solutions. This study introduces a novel, low-cost, Raspberry Pi-based system for real-time monitoring and automated biomass recovery in microalgal cultivation. The system integrates turbidity, light, pH, and temperature sensors with an automated module for harvesting and medium replenishment. Cultures of the filamentous, spiral-shaped microalga Limnospira fusiformis were used to evaluate system performance. The turbidity sensor showed strong correlation with optical density (R
