Histological study on the effect of nicotine on adult male guinea pig thin skin.
Article in Anatomy & cell biology, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Tobacco smoking has been identified as an important factor in premature skin aging to detect the histological changes occurred in adult male guinea pig thin skin under the influence of low and high doses of nicotine; which constitutes approximately 0.6%-3.0% of the dry weight of tobacco. Fifteen adult male pigmented guinea pigs were equally divided into three groups: group I, control; group IIA, low dose nicotine treated; 3 mg/kg subcutaneously for 4 weeks; and group IIB, high dose nicotine treated; 6 mg/kg subcutaneously for 4 weeks. Specimens from the back thin skin were processed for light and electron microscopy. Nicotine administration revealed flattened dermo-epidermal junction and reduced rete ridges formation. Collagen bundles were disorganized with increased spaces between them. A reduction in the amount of elastic fibers in the dermis were also observed compared to group I. Ultrastructurally, keratinocytes had hyperchromatic nuclei, intracytoplasmic vacuoles, disruption of desmosomal junctions, irregular tonofilaments distribution, and increased inter-cellular spaces. These changes were more pronounced with high dose nicotine administration. The epidermal thickness was reduced in low dose nicotine administration. But, high dose nicotine administration revealed increased epidermal thickness compared to the control group. Nicotine induced structural changes of adult male guinea pig thin skin. These changes were more pronounced with high dose nicotine administration.
