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

Bacillus subtilis strain AF2 was obtained from the Mediterranean Sea and its identification was determined by its phylogenetic analysis of 16S rRNA sequences, as well as their morphological, physiological, and biochemical characteristics. The isolate yielded EPSS4 at a concentration of 7.4 g/l. EPSS4 constituted a significant proportion of the EPS recovered through purification using DEAE-Cellulose. The sample consisted of sulfate (24.71%) and uronic acid (18.55%). The fraction's viscosity was measured to be 1.1 mm
