1 · What the graph read from it

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.

2 · The registry

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

To find an alternative approach to the in vivo detection of tumor necrosis factor/cachectin (TNF alpha), an immunohistochemical method to identify TNF alpha in histologic sections was developed. This method employs the streptavidin-biotin immunoperoxidase technique, and TNF alpha-specific monoclonal and polyclonal antibodies, on cryostat sections of fresh frozen human lymphoid tissue. Staining was evident in most specimens displaying follicular hyperplasia, but was absent from histologically normal tissue. Both tingible body macrophages and follicular dendritic reticulum cells appeared from phenotype analysis in serial sections and by double staining experiments to constitute the main source of TNF alpha. This technique complements other systemically oriented assays that may fail to detect significant in vivo TNF alpha production and activity at a cellular level.
