Heat-induced antigen retrieval for immunohistochemical reactions in routinely processed paraffin sections.
Article in Methods in molecular biology (Clifton, N.J.), 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 50 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
The development of heat-induced antigen (epitope) retrieval (HIER) technologies has led to dramatic improvements in our ability to detect antigens in formalin fixed, archival tissues. Paradoxically, wet heat treatment at temperatures greater than 95 degrees C in appropriate buffer solutions can reconstitute the antigenicity of many proteins that have been rendered nonreactive during the fixation and paraffin embedding process, which heretofore could only be identified in fresh or frozen tissues. The reason for this effect is unclear, but it has been suggested that the vigorous heat treatment partially reverses or disrupts the aldehyde cross-links occurring in proteins during formalin fixation and restores the original conformation of antigenic epitopes. The great success of antigen/epitope retrieval technologies further emphasizes the importance of preanalytical steps in immunohistochemistry. Over the past several years, since this technology was first reported, there have been numerous modifications to the original formulation. It is the purpose of this chapter to discuss the critical issues required for optimal HIER and to provide guidelines for the use of popular HIER buffers and heating devices used for routine immunohistochemical detection.
