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

Microalgae are recognized as eco-functional inoculants that improve soil quality and stimulate plant productivity. This study explored the potential of pyroligneous acid (PA), a low-cost byproduct of biomass pyrolysis, as a biostimulant enhancing microalgal growth and metabolite production. We investigated the effects of PA on growth, and synthesis of indole-3-acetic acid (IAA) and extracellular polymeric substances (EPS) in two microalgal strains, Desmodesmus sp. MAS1 and Chlorella sp., when cultivated with PA in presence or absence of light. Preliminary studies showed that 0.01% (v/v) of PA enhanced growth of the microalgae, and its increased concentrations were inhibitory. Growth rate of Chlorella sp. with PA was 0.444 d
