Positive association between actinic keratosis and internal malignancies: a nationwide population-based cohort study.
Article in Scientific reports, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Little is known about the comorbidities in actinic keratosis patients. To evaluate the association of actinic keratosis with certain malignancies. All patients with actinic keratosis (n = 61,438) and age- and sex-matched control subjects (n = 307,190) at a 5:1 ratio were enrolled using data from the Korean National Health Insurance Service between the years 2007 and 2014. In subjects with actinic keratosis, overall cancer incidence was higher than that for controls after income level, habitat, diabetes, hypertension, and dyslipidemia were adjusted (Hazard Ratio [HR] = 1.43 [95% confidence interval 1.38-1.47]). The positive association of specific cancers were observed in the following order: skin cancer (HR = 3.43 [2.47-4.75]), oral cavity and pharyngeal cancer (HR = 1.99 [1.57-2.52]), lymphoma (HR = 1.59 [1.28-1.96]), leukemia (HR = 1.35 [1.03-1.77]), prostate cancer (HR = 1.35 [1.21-1.51]), renal cancer (HR = 1.29 [1.02-1.63]), liver cancer (HR = 1.21 [1.09-1.35]), thyroid cancer (HR = 1.20 [1.05-1.38]), and gastric cancer (HR = 1.13 [1.03-1.23]). Although further research on pathologic mechanism is needed, the implications of a positive correlation between actinic keratosis and internal organ malignancies has great significance.
