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 present study evaluated a commercial device for peripheral quantitative computed tomography (pQCT) and examined the age-related changes in normal Japanese women. The volumetric bone mineral density (vBMD) of the distal radius [integral bone mineral density (BMDI), trabecular bone mineral density (BMDT) and cortical with subcortical bone mineral density (BMDSC)] was measured using pQCT (Norland-Stratec XCT960) in 617 healthy women aged 20-79 years and 75 subjects with osteoporosis aged 60-89 years who exhibited at least one vertebral fracture. The short-term precision errors in vivo (CV, %) were 1.1% for BMDI, 1.1% for BMDT and 1.2% for BMDSC. The correlations between pQCT and dual-energy X-ray absorptiometry measurements (Lunar DPX) of the lumbar spine were r approximately 0.8 (BMDI, BMDT and BMDSC). The maximal mean vBMD values were observed between 20 and 49 years; BMDI, BMDT and BMDSC all showed a linear postmenopausal decline averaging 1.1% per year. The overall decreases in vBMD from the peak values in those 70-79 years were 34%, 32% and 33% in BMDI, BMDT and BMDSC, respectively. The diagnostic sensitivity of osteoporosis was expressed as a T-score. T-scores using pQCT were -3.0 (BMDI), -2.4 (BMDT) and -2.9 (BMDSC). Bone mineral measurement of the distal radius may be useful in the evaluation of age-related bone loss and for the diagnosis of osteoporosis.
