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
TATA-binding protein (TBP)-interacting protein from the hyperthermophilic archaeon Thermococcus kodakaraensis strain KOD1 (Tk-TIP26) is a possible transcription regulatory protein in Thermococcales. Here, we report the crystal structure of Tk-TIP26 determined at 2.3 A resolution with multiple-wavelength anomalous dispersion (MAD) method. The overall structure of Tk-TIP26 consists of two domains. The N-terminal domain forms an alpha/beta structure, in which three alpha-helices enclose the central beta-sheet. The topology of this domain is similar to that of holliday junction resolvase Hjc from Pyrococcus furiosus. The C-terminal domain comprises three alpha-helices, six beta-strands, and two 3(10)-helices. In the dimer structure of Tk-TIP26, two molecules are related with the crystallographic twofold axis, and these molecules rigidly interact with each other via hydrogen bonds. The complex of Tk-TIP26/Tk-TBP is isolated and analyzed by SDS-PAGE and gel filtration column chromatography, resulting in a stoichiometric ratio of the interaction between Tk-TIP26 and Tk-TBP of 4:2, i.e., two dimer molecules of Tk-TIP26 formed a complex with one dimeric TBP. The electrostatic surfaces of Tk-TIP26 and TBP from Pyrocuccus woesei (PwTBP) allowed us to build a model of the Tk-TIP26/TBP complex, and to propose the inhibition mechanism where two dimer molecules of Tk-TIP26 bind to a dimeric TBP, preventing its binding to TATA-DNA.
