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
We conducted an in vitro investigation of the selective cytotoxicity of alpha-emitting radioimmunoconjugates (α-RICs) directed against cells expressing HIV envelope (Env) proteins. It is well known that monoclonal antibody (mAb)-targeted α-emitting radionuclides can effectively kill antigen-expressing cells; however, the expected low-level expression of HIV antigens on latently infected cells poses an obstacle to all anti-HIV immune-based treatments, including α-RICs. This investigation tested the cytotoxicity of the HIV envelope antigen-binding mAbs, PGT126 (binding gp120) and 7B2 (binding gp41), conjugated with labeling chelators that bind the α-emitters astatine-211 (
methodsHigh specific activity (SA) preparations of the α-RICs were made to increase the proportion of mAb conjugates carrying the α-emitting isotope. RIC cytolytic activity was evaluated against a cell line stably expressing the HIV envelope.
