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
In the Caribbean there is limited data on orthostatic hypertension (OHT) in elderly hypertensive patients with atherosclerotic disease who are at risk for cardiovascular events. The authors examined the association of antihypertensive classes of drugs with diastolic OHT in patients 60 year and older with hypertension and hyperlipidemia attending public primary care facilities. These relationships were evaluated in a cross-sectional study of hypertensive hyperlipidemic older patients (n = 400) to determine orthostatic changes in blood pressure based on seated to standing measurements. OHT was defined as an increase in systolic blood pressure of ≥20 mm Hg and/or increase in diastolic blood pressure of ≥10 mm Hg upon orthostasis at 3 min. Patients were categorized based on their orthostatic blood pressure response: orthostatic normotensive (n = 200) and blood pressure dysregulated (n = 200) of which 168 were diastolic OHT. Multivariable logistic regression models were used to examine associations of antihypertensive classes and diastolic OHT. Renin-angiotensin-aldosterone-system (RAAS) blockers were the most commonly prescribed (79.3%), followed by diuretics (DIUs) (61.6%), dihydropyridine calcium channel blockers (dCCBs) (53.8%), and beta-blockers (BBs) (19.3%). Most normotensive (76.0%) and diastolic OHT (75.0%) patients were prescribed two or more antihypertensive medications. Pharmaceutical prescription of triple combination RAAS blockers + dCCBs + DIUs (OR, 0.55; 95% CI, 0.31-0.99) or RAAS blockers + dCCBs + BBs (OR, 0.23; 95% CI, 0.06-0.92) showed a protective effect of diastolic OHT in analyses adjusted for age, sex, sitting diastolic blood pressure, and comorbidities. Our study suggests prescription of triple combination antihypertensive drugs of RAAS blockers + dCCBs + DIUs or RAAS blockers + dCCBs + BBs may reduce the likelihood of diastolic OHT.
