High-precision automated bone age: a clinically useful tool in monitoring of treatment effects in children and adolescents.
Article in Scientific reports, 2026. 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
The clinical value of serial bone age (BA) determinations in children during growth is limited by the manual rater variability (precision 0.63 years). The objective of this work was to determine the precision of automated bone age and bone health index (BHI) measurements by BoneXpert and to establish the time interval at which the automated method can detect a significant treatment effect. The data were from a case-control trial (oxandrolone/placebo) following 90 boys with Klinefelter syndrome (KS) with five visits over 2 years, recording X-rays of both hands. The precision of BA was 0.08 years [0.07; 0.09] 95% CI, leading to a minimal detectable difference of 0.23 years. The effect of androgen treatment on BA was 0.24, 0.77, 1.24 and 1.43 years after 6, 12, 18 and 24 months, respectively. Thus, the effect on BA was detectable by 6 months. In conclusion, automated BA determination is markedly more precise, compared to manual X-ray readings and can detect 0.23 years changes. Automated BA is clinically useful in follow-up in children and adolescents during growth-modulating therapies.
