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
backgroundThis study aimed to identify associations of sarcopenia, obesity and low bone mineral density (BMD) with morning positional vertigo (PV) and to examine whether these associations differ according to vestibular function status in a nationally representative sample of Korean adults.
methodsWe analysed data from 8512 adults aged ≥ 40 years (50.03% women, mean ± standard error [SE] = 54.06 ± 0.19) who participated in the Korean National Health and Nutrition Examination Survey 2008-2010. Morning PV was defined as severe vertigo when turning in bed or rising in the morning within the past year. Vestibular impairment was assessed using the modified Romberg test (eyes closed, standing on a compliant foam surface). Participants were classified into three groups: controls (no dizziness), morning PV with normal Romberg test results and morning PV with abnormal Romberg test results (suggesting vestibular dysfunction). Body composition-including appendicular skeletal muscle mass, fat mass and BMD-was measured. Sarcopenia was defined according to the Asian Working Group for Sarcopenia 2019 criteria, and abnormal BMD was defined as T-score < 1.0. Weighted multinomial logistic regression analyses were adjusted for age, sex, income, comorbidities, lifestyle and psychosocial variables.
resultsThe weighted 1-year prevalence of morning PV was 12.58% (95% confidence interval [CI], 11.38-13.89). Abnormal Romberg performance, indicating vestibular dysfunction, was present in 0.96% of all survey respondents and in 7.66% of those with morning PV. Participants with vestibular-impaired morning PV were older (mean age ± SE = 66.47 ± 1.49), predominantly women, and had higher rates of sarcopenia (38.33%) and low BMD (86.39%) than controls. In adjusted models, sarcopenia independently predicted vestibular-impaired morning PV (odds ratio [OR], 1.94; 95% CI, 1.14-3.29; p = 0.014). Sensitivity analysis restricted to current morning PV confirmed the association between sarcopenia and vestibular impairment (OR, 2.97; 95% CI, 1.08-8.12; p = 0.035) and demonstrated that lower BMD (minimum T-score) was inversely associated with vestibular dysfunction (OR, 0.49; 95% CI, 0.25-0.99; p = 0.046).
conclusionsMorning PV is common among middle-aged and older adults and is associated with systemic frailty markers, particularly sarcopenia and bone loss, in the presence of vestibular dysfunction. These associations were more pronounced in older adults, suggesting a vestibulo-musculoskeletal interaction that may contribute to balance impairment and functional decline with aging. Screening for sarcopenia and bone health, along with vestibular and lifestyle interventions, may help reduce recurrent vertigo and improve functional aging.
