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.
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
A strictly anaerobic bacterium, strain B5(T), was isolated from sediment of an abandoned coal mine in Taebaek, Republic of Korea. Cells of strain B5(T) were non-spore-forming, straight, Gram-positive rods. The optimum pH and temperature for growth were pH 7.0 and 30°C, respectively, while the strain was able to grow within pH and temperature ranges of 5.5-7.5 and 25-45°C, respectively. Growth of strain B5(T) was observed at NaCl concentrations of 0 to 6.0% (w/v) with an optimum at 3.0-4.0% (w/v). The polar lipids consisted of phosphatidylethanolamine, phosphatidylglycerol, an unknown phospholipid and three unknown polar lipids. Strain B5(T) grew anaerobically by reducing nitrate, nitrite, ferric-citrate, ferric-nitrilotriacetate, elemental sulfur, thiosulfate, and anthraquinone-2-sulfonate in the presence of proteinaceous compounds, organic acids, and carbohydrates as electron donors. The isolate was not able to grow by fermentation. Strain B5(T) did not grow under aerobic or microaerobic conditions. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain B5(T) is most closely related to the genus Tepidibacillus (T. fermentans STGH(T); 96.3%) and Vulcanibacillus (V. modesticaldus BR(T); 94.6%). The genomic DNA G+C content (36.9 mol%) of strain B5(T) was higher than those of T. fermentans STGH(T) (34.8 mol%) and V. modesticaldus BR(T) (34.5 mol%). Based on its phenotypic, chemotaxonomic, and phylogenetic properties, we describe a new species of a novel genus Calculibacillus, represented by strain B5(T) (=KCTC 15397(T) =JCM 19989(T)), for which we propose the name Calculibacillus koreensis gen. nov., sp. nov.
