A Correlation between Serum Level of Alkaline Phosphatase and Acne Severity in Children and Adolescents: A Retrospective Cross-Sectional Study.
Article in Annals of dermatology, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundAcne is a chronic inflammatory disease of the pilosebaceous unit and usually affects adolescents when the peak concentrations of growth hormone, insulin-like growth factor 1, and androgen are demonstrated. The activity of alkaline phosphatase (ALP), which increases physiologically in growing children and adolescents, in the pilosebaceous unit has been reported. However, the correlation between the serum level of ALP and the number of acne lesions has not been studied.
objectiveThe present cross-sectional study was designed to evaluate the correlation between serum level of ALP and the numbers of non-inflammatory and inflammatory acne lesions in children and adolescents.
methodsFor this study, 202 pediatric and adolescent patients clinically diagnosed with acne vulgaris were included. Age, sex, serum level of ALP, number of non-inflammatory acne lesions, number of inflammatory acne lesions, and number of total acne lesions were evaluated. Additionally, the serum level of dehydroepiandrosterone sulfate was evaluated in 117 patients. Multiple regression analysis was performed. Multicollinearity was quantified using the variance inflation factor.
resultsIn the 202 patients, serum level of ALP was the only independent factor that significantly affected both the number of non-inflammatory acne lesions and of total acne lesions (regression coefficient=0.089 and 0.086, respectively,
conclusionThere was a significant correlation between serum level of ALP and the extent of acne (non-inflammatory acne lesions and total acne lesions).
