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 finding that basal forebrain cholinergic cells are specifically endowed with the low-affinity nerve growth factor receptor p75NTR has been employed to develop a cholinergic immunotoxin in rats by covalently linking the monoclonal antibody 192IgG against the rat p75NTR with the cytotoxic protein saporin (192IgG-saporin). Following intracebroventricular application of 192IgG-saporin, the antibody conjugate is taken up into cholinergic cells via the p75NTR, retrogradely transported to the cell body, where saporin exerts cytotoxic action. The lack of an appropriate antibody directed against mouse p75NTR has been hampered the development of a mouse-specific cholinergic immunotoxin, which should be a useful tool to study effects of cortical cholinergic deficits on processing of amyloid precursor protein in transgenic mice with Alzheimer pathology. To develop an appropriate mouse-specific immunotoxin, a variety of antibodies directed against mouse p75NTR were tested. Using double labeling immunocytochemistry, the rat monoclonal antibody CHO5 against mouse p75NTR was found to label mouse basal forebrain neurons, which also demonstrated immunoreactivity for choline acetyltransferase and the high-affinity nerve growth factor receptor, TrkA. Intracerebroventricular infusion of CHO5 in mice resulted in an accumulation of the antibody in cholinergic cells within the basal forebrain, suggesting that CHO5 is a suitable candidate to develop a mouse-specific cholinergic immunotoxin.
