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

Microbially induced calcium carbonate precipitation (MICCP) is a sustainable strategy for improving the mechanical strength and durability of cementitious materials through biologically mediated mineral precipitation. The performance of most ureolytic bacteria declines under saline conditions, limiting their use in marine environments. This study evaluates the genomic and functional adaptation of the halotolerant ureolytic bacterium Bacillus paramycoides MSR1, isolated from Sambhar Lake, Rajasthan, India, for MICCP-based applications in saline construction environments. B. paramycoides retained high urease (590 U/mL) and carbonic anhydrase (90 U/mL) activities and precipitated 180 mg/100 mL of calcium carbonate after 7 days at 3.5% NaCl concentration, equivalent to seawater salinity, while continuing to demonstrate effective biomineralization up to 5% NaCl concentration. Therefore, 3.5% NaCl was selected for mortar casting and curing to simulate marine conditions. Incorporation of B. paramycoides in mortar specimens cast and cured under 3.5% saline conditions (BS) increased 28-day compressive strength by 15.28% and reduced sorptivity from 0.0043 to 0.0007 cm s
