The Variability and Determinants of Testosterone Measurements in Children: A Critical Review.
Review in Biological research for nursing, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
aimsThis critical review aimed to summarize: (1) the variability and determinants of testosterone (T) measurements; and (2) reference values for the variability and determinants of T measurements in children.
backgroundAs T is a representative androgen, it has been widely used to explain male vulnerability to child health and developmental problems. T measurements in children, however, have been challenging because of low levels, diurnal and episodic secretion patterns, limited quantity and quality of the samples, and inconsistent study findings.
methodsThe search strategy used PubMed, CINAHL, Cochrane Library, Embase, Scopus, and Google Scholar. Studies published between 2008 through 2020 that examined factors influencing T measurement were included. The final 30 studies were selected using two appraisal forms. We extracted five categories of data from the reports.
findingsVariability and determinants of T measurement included assay methods, the source of samples, and child demographic and environmental characteristics. T levels were higher 1-3 months after birth and in males up to 1 year; fewer sex differences were found up to 10-12 years. Serum T levels measured by using liquid chromatography-mass spectrometry were most reliable because immunoassays overestimated the levels, especially in neonates. T levels were stable at different temperatures and durations of storage, although sample collection remained an ongoing challenge for researchers.
conclusionDepending on the study aims and feasibility, mass-spectrometry, multi-methods, and multi-materials are the recent trends in T measurement. Immunoassays may be an option if the study aims for relative rather than absolute comparisons.
