Cross-reactivity of the anti-La monoclonal antibody SW5 with early endosome antigen 2.
Article in Immunology, 2002. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Coimmunoprecipitation studies with SW5, a frequently used and specific mouse monoclonal antibody (mAb) directed against the human La autoantigen, led to the identification of a functionally unrelated 80 000 MW protein, designated early endosome antigen 2 (EEA2). EEA2 appeared to be directly targeted by mAb SW5. Because an RNA-binding domain, a structural element of La containing the SW5-epitope, was not discernable in the primary structure of EEA2, the SW5-epitope on EEA2 was determined. Coiled-coil region 3 of EEA2 appeared to contain the epitope recognized by SW5. The SW5 epitope regions of La and EEA2 share a limited sequence homology and probably share a higher degree of structural similarity at the tertiary level. Most likely, the most critical determinants for recognition by SW5 reside in elements adopting alpha-helical conformations. These data indicate that the application of specific mAbs to purify and characterize (functionally) interacting proteins can be severely obscured by the cross-reactivity of mAbs with structurally, but not functionally, similar proteins.
