Lewis-X-Containing Triterpenoid Saponins Inhibit DC-SIGN- and L-SIGN-Mediated Transfer of HIV-1 Infection.

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
Blocking dendritic cell-specific intercellular adhesion molecule-3-grabbing nonintegrin (DC-SIGN)- and liver/lymph node-specific intercellular adhesion molecule-3-grabbing integrin (L-SIGN)-mediated human immunodeficiency virus 1 (HIV-1) attachment to immune cells represents a promising strategy for developing antiretroviral agents effective during the early stages of sexual transmission. Although mannose- and fucose-based ligands have received considerable attention, Lewis-based inhibitors remain relatively underexplored. In this study, we report the first synthesis of Lewis-X-containing triterpenoid saponins featuring betulinic acid and echinocystic acid as aglycones. These saponins were stereoselectively and efficiently synthesized in six linear steps using a convergent approach that leveraged thioglycoside and trichloroacetimidate glycosylation chemistries. Notably, our findings demonstrate that these Lewis-X-containing triterpenoid saponins are among the most potent monovalent inhibitors reported to date of DC-SIGN- and L-SIGN-mediated transfer of HIV-1 infection to CD4-positive cells, with IC
