[Prevalence and relations of orthostatic hypotension in patients 80 years old and over from a primary care unit].
Observational study in Atencion primaria, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveTo estimate the prevalence of orthostatic hypotension (OH) in patients 80 years old and over attending a primary care unit. To relate OH to the most prevalent pathologies and to the most used drugs.
designTransversal observational study. LOCATION: Primary care unit, Santiago de Compostela.
participantsEighty one patients 80 years old or over representative of a primary care unit were recruited. Ten patients were excluded. MAIN MEASUREMENTS: Blood pressure was measured in decubitus and later in erect position first immediately after standing and then after 3 minutes. Diagnoses and active treatments were reviewed in the electronic clinical history and through an interview with the patient and caregiver.
resultsIn 26.76% of patients the systolic blood pressure fell by 20mmHg or more and/or the diastolic blood pressure fell by 10mmHg in the instant following the postural shift. In 16.90% of patients the drop persisted after 3 minutes of standing from decubitus position. None of the patients was diagnosed with OH. The highest prevalence ratio was observed for diabetes mellitus (1.6; P=.412), not existing differences for arterial hypertension (P=.881). OH related in a statistically meaningful way to the use of renin angiotensin aldosterone system inhibitors (OR: 8.174, CI95%: 1.182-56.536); P=.033] and benzodiazepines (OR: 5.938, CI95%: 1.242-28.397; P=.026)].
conclusionOH had a prevalence of 16.90% among the elderly patients who had a consultation. Its connection with some drugs (renin angiotensin aldosterone system inhibitors and benzodiazepines) must be considered.
