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

Concrete can be engineered with self-healing capabilities using bacteria, providing an eco-friendly and sustainable alternative to traditional repairs. This research evaluated the biocementing potential of Bacillus sp. and Streptomyces sp. by analyzing their resistance to stress conditions (pH 8 and 10) and their ability to produce calcium carbonate. Both strains showed stable growth; however, Bacillus sp. generated a higher formation of crystals, identified as vaterite and syn-vaterite, confirmed by SEM and EDS. In sand columns, Bacillus sp. increased cohesion thanks to the formation of cementing bridges with high surface area, while Streptomyces sp. showed limited action. The results demonstrate that Bacillus sp. is the more promising candidate for the development of sustainable self-healing concrete.
