A Sequence-Based Approach Reveals a Novel Family IV Lipolytic Enzyme in Cereibacter sphaeroides 2.4.1.
Article in Molecular biotechnology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Bacterial lipases and esterases are central to lipid metabolism and biotechnology, yet they are underexplored in purple non-sulfur photosynthetic bacteria. To address this gap, we mined the genome of Cereibacter sphaeroides 2.4.1 by retrieving the sequences annotated by alpha beta hydrolase, esterase, and lipase from NCBI database. All sequences aligned to well-known of bacterial esterase or lipase and the higher identity was cloned and expressed in Escherichi coli. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) confirmed soluble expression of four proteins, with LipCs2 (26.4 kDa), LipCs3 (39.4 kDa), and LipCs9 (24.1 kDa) showing activity on tributyrin agar and preference for short-chain para-nitrophenyl esters. Although LipCs9 (314.11 ± 2.44 mM h
