1 · What the graph read from it

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.

2 · The registry

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 goal of this study is to investigate the causes of skeletal fragility in type 1 diabetic (T1D) women. We hypothesize that bone fragility in diabetic individuals is partly due to changes in mineral and/or intrinsic material properties in the osteocyte lacunar/peri-lacunar regions of bone tissue. Studies of bone material properties in T1D are limited, and BMD alone does not explain the elevated fracture risk in T1D women (Cases). Innovative instruments with nanoscale resolution, including a laser scanning microscope, an atomic force microscope that is integrated with infrared spectroscopy, and a nanoindenter, were used for the characterization of the material properties surrounding osteocyte lacunae. In trabecular bone tissue, the compositional Mineral Matrix Area (MMA) and MMP ratios (for both near- & far-lacunae), along with material strength variables (Modulus, Hardness for both near- & far-lacunae), were lower in T1D compared to Controls. While the material compositional ratio of mineral maturity, crystallinity, and area was higher, the mineral maturity, crystallinity peak, and hardness tended to be higher in "lacunae-near" than "lacunae-far" for all the biopsies. Furthermore, the higher mineral matrix (MMA) and material strength (modulus, hardness) in peri-lacunar regions of Controls may suggest its increased brittleness or differences in properties as compared to T1D. We postulate that the difference between Cases (T1D) and Controls in modulus and hardness could be due to the variation in mineral exchange (diffusion) rate within the perilacunar space.
