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
A cDNA clone for an IgG-binding Fc receptor, rtFc gamma R alpha, of the rat natural killer cell line CRNK-16 is characterized here. This clone encodes an Fc gamma receptor as shown by the ability of cDNA-transfected COS cells to rosette IgG-coated sheep erythrocytes. The rtFc gamma R alpha is exceptionally homologous to the mouse moFc gamma R alpha, with 77% protein sequence identity and 71% nucleic acid identity overall. The transmembrane region of the rtFc gamma R alpha contains the sequence Leu-Phe-Ala-Val-Asp-Thr-Gly-Leu, which is present in the membrane sequences of four other Fc receptors including mouse Fc gamma R alpha, human Fc gamma RIII-2, and the Fc epsilon R alpha subunits of the rat and human high-affinity IgE-binding receptors. Also, the rtFc gamma R alpha cytoplasmic domain exhibits specific homology to other receptors derived from natural killer cells, human Fc gamma RIII-2 and mouse Fc gamma R alpha. However, the rtFc gamma R alpha cDNA clone is complementary to at least two different-sized mRNAs expressed by CRNK-16 cells, contrasting the single Fc gamma R-related mRNA species expressed by human and mouse natural killer cells. These rat mRNAs are homologous to both the 5' and the 3' end of the cDNA clone, suggesting that they may be (i) splice variants of one transcript or (ii) products of different but highly related genes.
