Salivary Testosterone, Androstenedione and 11-Oxygenated 19-Carbon Concentrations Differ by Age and Sex in Children.
Article in Clinical endocrinology, 2025. 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
backgroundThe diagnosis and management of childhood adrenal disorders is challenging. Clinical markers of hormone excess or deficiency may take months to manifest, and traditional biomarkers correlate only partially with clinical outcomes. Recent work has indicated that 11 oxygenated 19-carbon (11oxC19) steroids may be useful in the assessment of adrenal function. 11oxC19 steroids, testosterone (T) and androstenedione (A4), can be measured in saliva, but very little is known about these hormones in healthy children.
methodsParticipants collected saliva samples 30 min after waking and every 2 h until bedtime. Samples were analysed for T, A4, 11 ketotestosterone (11KT) and 11βhydroxyandrostenedione (11OHA4) by liquid chromatography tandem mass spectrometry.
resultsFifty-two (30 male) healthy children aged 10.4 ± 3.9 (5.0-17.5) participated. Median height SDS was 0.4 (IQR -0.3 to 1.01) and median BMI SDS was 0.3 (IQR -0.2 to 1.3). All steroids showed a diurnal rhythm, with all hormones decreasing in measured concentration at time points that are 30 min after waking. Salivary T was higher in postpubertal children, particularly boys (p < 0.001). Salivary A4 was lower in boys compared to girls (p = 0.009) and did not differ with pubertal development. 11KT increased with age (p < 0.001) and concentrations were similar between boys and girls. 11OHA4 reduced in concentration with age (p = 0.03) and was below detectable limits after the early morning peak in both sexes.
conclusionFor the first time we describe the physiological profile of 11KT and 11OHA4 in children. Further data are required to establish reference ranges, which should consider age, sex, pubertal status and time of sampling.
