Submaximal exercise coronary artery flow increases in postmenopausal women without coronary artery disease after estrogen and atorvastatin.
Trial report in Menopause (New York, N.Y.). The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
objectiveThe aim of this study was to determine the effect of statins and hormone therapy on submaximal exercise-induced coronary artery blood flow in postmenopausal women without a history of coronary artery disease. Hormone therapy or statin therapy in early postmenopausal women without coronary artery disease has been shown to enhance arterial endothelial function; we hypothesized that these agents would improve submaximal exercise-induced coronary artery blood flow.
methodsSixty-four postmenopausal women, aged 50 to 65 years without documented coronary artery disease, were randomized in a double-blind, crossover fashion to receive 8 weeks of hormone therapy versus placebo, with or without 80 mg/day of atorvastatin. Before receipt of any therapy and after each treatment period, each woman underwent measures of coronary artery blood flow at rest and stress.
resultsThe combination of hormone therapy and atorvastatin increased submaximal exercise-induced coronary artery blood flow (P = 0.04). In the subgroups of women compliant with treatment, resting coronary artery blood flow increased in those receiving hormone therapy (P = 0.03) or statin therapy (P = 0.02).
conclusionsIn postmenopausal women aged 50 to 65 years without documented coronary artery disease, resting and submaximal exercise-induced coronary artery blood flow improves after receipt of high-dose atorvastatin and conjugated estrogens therapy.
