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
Type 2 diabetes mellitus and lower weight are both associated with osteoporotic fractures, but the roles of variability and trajectory are less clear. The associations of these factors among older adults with dysglycemia, who are at highest risk of fracture, with fracture risk and BMD remain uncertain. We followed 775 men and 1080 women from the Cardiovascular Health Study (mean age 77.4 years) with abnormal oral glucose tolerance testing in 1989-1990. We measured their weights yearly through 1994-1995 and derived intra-individual mean weight, weight slope, and weight variability. We also used growth mixture modeling to derive 4 latent BMI trajectories over time. We used Cox proportional hazards models to calculate hazard ratios (HRs) and 95% CI for subsequent hip fracture through 2015 and linear regression models to estimate cross-sectional associations with BMD of the hip. Each 10 kg higher mean weight was associated with a lower risk of subsequent hip fracture overall (HR 0.81; CI, 0.70-0.94) and among women (HR 0.76; CI, 0.64-0.91) and with higher BMD (p <.001). Higher weight variability was directly associated with incident hip fracture among women (HR 1.18; CI, 1.03-1.35). Compared with a stable trajectory, a "progressive overweight" trajectory was associated with lower risk of hip fracture (HR 0.66; CI, 0.44-0.99). An uncommon trajectory of "accelerating obesity" was associated with higher BMD. Among older adults with dysglycemia at high risk for fracture, lower mean weight is associated with higher fracture risk, but variability and trajectory may also contribute. These results highlight the complex effects of weight in older age.
