Effects of macrophage activity on the antibody-dependent cytotoxicity against Trichinella spiralis newborn larvae: an in vitro cytotoxicity and ultrastructural study.

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 effect of the activity of macrophages on the antibody-dependent cytotoxicity against Trichinella spiralis newborn larvae was studied in vitro. Macrophages present in peritoneal exudates from mice genetically selected for high and low antibody production (HL and LL, respectively) showed an inverse cytotoxic effect. Cells from HL mice were ineffective, whereas cells from LL mice had a very high killing capacity. Ultrastructural studies of cells after incubations of up to 36 h supported these observations. Furthermore, peritoneal macrophages from congenitally athymic (nu/nu) mice showed a higher killing potential than cells from thymus-bearing littermates (+/nu) mice. The activity of the latter cells could be increased by in vitro pretreatment of the mice with Calmette-Guérin bacillus, a well-known macrophage stimulating agent. The results indicate that macrophages, although not the only effector cells, may play an important role in the defence against T. spiralis newborn larvae.
