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

A cream-white bacterial colony designated SH1-B was isolated on Tryptone Soya Agar (TSA) plated with a brackish water sample collected from the Pichavaram mangrove forest. The strain SH1-B was Gram-stain negative, rod-shaped, motile, non-spore-forming aerobic bacterium. Catalase and oxidase activities were positive. Cells grew between 15 and 37 °C and pH 5.0–9.0. The nucleotide sequence of 16 S rRNA gene displayed high similarity with species of the genus Pseudomonas, including P. khazarica TBZ2T (98.5%), P. yangonensis MY50T (98.0%) and P. oleovorans subsp. oleovorans DSM1045T (98.0%). Genome sequence analysis of strain SH1-B showed 74.2–87.6% average nucleotide identity (ANI) with the type strains of the closest species. Additionally, digital DNA-DNA hybridization (dDDH) analysis revealed low relatedness, with a maximum value of 34.9% observed for its closest phylogenetic relative, P. khazarica TBZ2T. The G + C content of the genomic DNA was 62.2%. The major polar lipids were phosphatidylethanolamine (PE), phosphatidylglycerol (PG) and an unidentified phospholipid (PL1). The predominant cellular fatty acids of strain SH1-B included C18:1ω7c, C16:0, C12:0, summed feature 3 (C16:1ω6c/C16:1ω7c). Considering the phenotypic differences and low genomic identity compared to the closest species, strain SH1-B was identified as a novel species within the genus Pseudomonas, for which the name Pseudomonas pichavaramensis sp. nov. is proposed. The type strain is SH1-BT (= MTCC 13546T = JCM 37389T = ICMP 25819T).
