Immunohistochemical study of cell proliferation and differentiation in epidermis of mice after administration of cholera toxin.
Article in Archives of dermatological research, 1993. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Cholera toxin causes reversible epidermal hyperplasia. We observed maximal thickness of the epidermis on the fourth day after treatment and a return to pretreatment values by day 7. The increase in thickness occurred in the basal and intermediate layers, with these layers becoming two to three times thicker than those of normal epidermis. The time sequence of epidermal proliferation was studied using bromodeoxyuridine (BrdU) labelling. We observed a maximum number of labelled basal cells within the first 24 h. Only a few cells were labelled 7 days after toxin injection. Griffonia simplicifolia-IB4 (GSA-IB4), Ulex europaeus-I (UEA-I) and Griffonia simplicifolia-II (GSA-II) lectins were used for the analysis of epidermal cell differentiation in the tissue sections. To study keratinocyte differentiation, further immunological staining was performed using two anticytokeratin antibodies, PKK2 and PKK3 mouse monoclonal antibodies. From the immunocytochemical results, we conclude that synchronous differentiation of the epidermis occurs after cholera toxin administration.
