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

backgroundInitial orthostatic hypotension (OH) is a clinical syndrome of exaggerated transient orthostasis associated with higher risks of falls, frailty and syncope in older adults.

objectiveTo provide a prevalence estimate of initial OH in adults aged 65 years or older.

methodsLiterature search of MEDLINE (from 1946), Embase (from 1947) and Cochrane Central Register of Controlled Trials was performed until 6 December 2019, using the terms 'initial orthostatic hypotension', 'postural hypotension' and 'older adults'. Articles were included if published in English and participants were 65 years or older. Random effects models were used for pooled analysis.

resultsOf 5,136 articles screened, 13 articles (10 cross-sectional; 3 longitudinal) reporting data of 5,465 individuals (54.5% female) from the general (n = 4,157), geriatric outpatient (n = 1,136), institutionalised (n = 55) and mixed (n = 117) population were included. Blood pressure was measured continuously and intermittently in 11 and 2 studies, respectively. Pooled prevalence of continuously measured initial OH was 29.0% (95% CI: 22.1-36.9%, I2 = 94.6%); 27.8% in the general population (95% CI: 17.9-40.5%, I2 = 96.1%), 35.2% in geriatric outpatients (95% CI: 24.2-48.1%, I2 = 95.3%), 10.0% in institutionalised individuals (95% CI: 2.4-33.1%, I2 = 0%) and 21.4% in the mixed population (95% CI: 7.0-49.6, I2 = 0%). Pooled prevalence of intermittently measured initial OH was 5.6% (95% CI: 1.5-18.9%, I2 = 81.1%); 1.0% in the general population (95% CI: 0.0-23.9%, I2 = 0%) and 7.7% in geriatric outpatients (95% CI: 1.8-27.0%, I2 = 86.7%).

conclusionThe prevalence of initial OH is high in older adults, especially in geriatric outpatients. Proper assessment of initial OH requires continuous blood pressure measurements.
