Osteoporosis knowledge and health beliefs in ındividuals with myasthenia gravis: a cross-sectional controlled study.

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
objectiveThe aim of this study was to investigate knowledge and health beliefs regarding osteoporosis in individuals with myasthenia gravis.
methodsThis cross-sectional study included 40 individuals with myasthenia gravis and 40 healthy controls, who were selected among individuals accompanying patients at outpatient clinics and hospital support staff. Participants completed the Revised Osteoporosis Knowledge Test and the Osteoporosis Health Belief Scale. For individuals with myasthenia gravis, additional data were collected, including disease duration, current use of prednisolone, and clinical classification.
resultsIn the myasthenia gravis group, the mean total Revised Osteoporosis Knowledge Test score was 16.6±2.3, and the mean total Osteoporosis Health Belief Scale score was 146.4±6.1, with no statistically significant difference compared with the controls (p>0.05). The myasthenia gravis group had significantly higher "barriers to exercise" scores compared with controls (p<0.001). Only 37.5% of individuals with myasthenia gravis perceived themselves to be at risk of developing osteoporosis. In the patient group, educational level showed a strong positive correlation with both total Revised Osteoporosis Knowledge Test (r=0.756, p<0.001) and total Osteoporosis Health Belief Scale (r=0.313, p=0.005) scores, whereas disease duration showed no significant correlation. There was also no significant difference in total Revised Osteoporosis Knowledge Test and Osteoporosis Health Belief Scale scores between patients currently receiving prednisolone and those not receiving it (p>0.05).
conclusionThis study indicates that individuals with myasthenia gravis have inadequate knowledge and low perception of osteoporosis risk. To enhance early identification and prevent osteoporosis-related complications, implementing targeted educational and preventive strategies is essential in this vulnerable population.
