Reduction in HLA-DR antigen density on alveolar macrophages of smokers.
Article in Lung, 1991. 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
The expression of HLA class II genes is essential to the antigen-presenting function of monocytes and macrophages. With a new cytofluorometric method of single-cell analysis we investigated the density of HLA-DR antigen expression on alveolar macrophages (AM) of smokers. Although all AM of nonsmokers (100 +/- 1%) expressed HLA-DR antigens, only 79 +/- 12% of AM from smokers showed positive findings (p less than 0.001). Furthermore, the antigen density of those cells expressing this antigen was significantly reduced in smokers (p less than 0.001). The defective expression of class II genes on AM of smokers might contribute to the impaired antigen-presenting function found by some previous investigators.
