Benefits of dual-axis rotational coronary angiography in routine clinical practice.
Article in Heart and vessels, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers, 1 of them a synthesis that pooled 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.
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
Dual-axis rotational coronary angiography (DARCA) is a new imaging technique involving three-dimensional rotation of the gantry around the patient with simultaneous left to right and craniocaudal movements. This allows complete imaging of the left or right coronary tree with a single acquisition run. Previous small studies have indicated that DARCA is associated with reduced radiation dose and contrast use in comparison with standard coronary angiography (SCA). We conducted a registry of unselected patients undergoing DARCA or SCA. DARCA was used in 107 patients and SCA in 105 patients. Mean number of acquisition runs was 2.6 for DARCA and 6.9 for SCA (P < 0.0001). Mean radiation dose (dose-area product, DAP) was 30.4 Gy cm(2) for SCA and 15.9 Gy cm(2) for DARCA (P < 0.0001). Mean contrast volume was 41.7 ml for SCA and 25.7 ml for DARCA (P < 0.0001). Case time for DARCA in the first half of the study was 20.8 ± 1.4 min compared with 15.2 ± 2.0 min in the second half of the study (P = 0.0015), suggesting a learning curve. In the DARCA group, 64 % of patients required only two acquisition runs for complete and satisfactory imaging. There were no adverse effects resulting from DARCA. Two cases are presented to illustrate the diagnostic ability of DARCA. DARCA was associated with a 48 % reduction in radiation dose and 36 % reduction in contrast volume in comparison with SCA, with comparable diagnostic ability.
