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
purposeIdiopathic juvenile osteoporosis (IJO) is a rare condition in children, characterized by bone pain and long bone and vertebral fractures. Previously, IJO bone was solely characterized by histomorphometry and quantitative computed tomography. The goal of this study is to describe IJO bone composition. MATERIALS AND
methodsFourier transform infrared imaging (FTIRI), a vibrational spectroscopic technique providing spatially resolved images of chemical composition, was used to determine whether iliac crest biopsies from children with IJO differed in composition from and age- and sex-matched controls, and, as a secondary analysis, whether IJO bone showed the same disease dependent change in composition as do iliac crest bone biopsies from women with post-menopausal osteoporosis (PMO). Wilcoxon rank tests and linear regressions were used to analyze FTIRI variables (mineral-to-matrix ratio, carbonate-to-phosphate ratio, crystallinity, acid phosphate substitution, collagen maturity) and their individual pixel distributions (heterogeneity).
resultsMineral-to-matrix ratio was comparable in IJO and age-matched controls. Contrastingly, collagen maturity (also known as collagen cross-link ratio) was higher in cortical and cancellous IJO bone compared with juvenile controls. Acid phosphate substitution was greater in IJO cancellous bone than in age-matched controls, suggesting IJO bone mineral is formed more recently, reflecting a slower mineralization process. This agrees with findings of increased heterogeneity for mineral-to-matrix and collagen maturity ratios in IJO cancellous bone. There were negative correlations between cancellous collagen maturity and previously reported histomorphometric bone formation markers. There were no correlations with indices of remodeling.
conclusionsIJO bone, similar to PMO bone, had elevated collagen maturity relative to its age-matched controls. This emphasizes the importance of the collagen matrix for bone health. IJO bone differed from PMO bone as IJO bone contains more recently formed mineral than age-matched controls but has a more mature matrix, whereas in PMO bone both mineral and matrix have older characteristics.
