Mortality implications of angina and blood pressure in hypertensive patients with coronary artery disease: New data from extended follow-up of the International Verapamil/Trandolapril Study (INVEST).

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
backgroundAngina and hypertension are common in patients with coronary artery disease (CAD); however, the effect on mortality is unclear. We conducted this prespecified analysis of the International Verapamil/Trandolapril Study (INVEST) to assess relationships between angina, blood pressure (BP), and mortality among elderly, hypertensive CAD patients. HYPOTHESIS: Angina and elevated BP will be associated with higher mortality.
methodsExtended follow-up was performed using the National Death Index for INVEST patients in the United States (n = 16 951). Based on angina history at enrollment and during follow-up visits, patients were divided into groups: persistent angina (n = 7184), new-onset angina (n = 899), resolved angina (n = 4070), and never angina (n = 4798). Blood pressure was evaluated at baseline, during drug titration, and during follow-up on-treatment. On-treatment systolic BP was classified as tightly controlled (<130 mm Hg), controlled (130-139 mm Hg), or uncontrolled (≥140 mm Hg). A Cox proportional hazards model was created adjusting for age, heart failure, diabetes, renal impairment, myocardial infarction, stroke, and smoking. The angina groups and BP control groups were compared using the never-angina group as the reference.
resultsOnly in the persistent-angina group was a significant association with mortality observed, with an apparent protective effect (hazard ratio: 0.82, 95% confidence interval: 0.75-0.89, P < 0.0001). Uncontrolled BP was associated with increased mortality risk (hazard ratio: 1.29, 95% confidence interval: 1.20-1.40, P < 0.0001), as were several other known cardiovascular risk factors.
conclusionsIn hypertensive CAD patients, persistent angina was associated with lower mortality. The observed effect was small compared with other cardiovascular risk factors, such as BP, which were associated with increased mortality.
