[Clinical effect of letrozole in treatment of idiopathic short stature in adolescent boys].
Article in Zhongguo dang dai er ke za zhi = Chinese journal of contemporary pediatrics, 2019. 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
objectiveTo evaluate the therapeutic effect and safety of letrozole in the treatment of adolescent boys with idiopathic short stature (ISS).
methodsA retrospective analysis was performed for the clinical data of 16 adolescent boys with ISS who had a bone age of ≥14 years. Among these boys, 8 were initially treated with recombinant human growth hormone (rhGH), followed by rhGH combined with letrozole during a bone age of 14-15.5 years. The other 8 boys were initially treated with rhGH combined with letrozole since their bone age was ≥14 years at diagnosis. Of the 16 boys, 16 were treated for not less than 6 months, 12 were treated for not less than 1 year, and 5 were treated for not less than 1.5 years. The increase in bone age, predicted adult height (PAH), final adult height, sex hormones, and adverse reactions after treatment were analyzed.
resultsAfter 6 months, 1 year, and 1.5 years of treatment, median bone age was increased by 0 year, 0.5 year, and 0.5 year respectively, which was significantly lower than the increase in age (P<0.05). There was a significant increase in PAH after treatment (P<0.05). Seven boys reached final height, which was significantly higher than PAH before treatment (P<0.05). All the 16 boys had significant increases in luteinizing hormone, follicle-stimulating hormone, and testosterone levels after treatment (P<0.05), with a significant reduction in the estradiol level and a significant increase in the insulin level at 1 year of treatment (P<0.05). There was a significant increase in the insulin-like growth factor-1 level at 6 months and 1 year of treatment (P<0.05). There were no significant changes in blood glucose, blood lipids, uric acid, and the three indices for thyroid function as monitored during treatment (P>0.05).
conclusionsIn adolescent boys with ISS and a high bone age, rhGH combined with letrozole can safely and effectively delay the increase in bone age and improve PAH and final adult height, with little adverse effect.
