Segmental distributions of calcifications and non-assessable lesions on coronary computed tomographic angiography: evaluation in symptomatic patients.
Article in Japanese journal of radiology, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
purposeTo clarify the frequency and distribution pattern of calcifications in all and in only non-assessable coronary arterial segments in symptomatic patients with coronary heart disease. MATERIALS AND
methodsAmong 2355 consecutive coronary CT angiographies performed using a 320-row ADCT, 1129 studies performed by prospective one-beat scanning without metallic and motion artifacts were evaluated. Frequency and degree of calcification were assessed for each coronary segment. Evaluations were performed in all and in only non-assessable segments, and the results were compared.
resultsCalcified segments were observed in 15.6 % of patients and 2.4 % of segments. The most extensively calcified segments were those in the proximal left anterior descending branch. 1.1 % of all of the segments were not assessable due to calcification, and 90 % of those non-assessable segments had high-grade calcifications. When the calcium score value was 1000 or 2000, the expected frequency of non-assessable segments was 27.5 or 53.5 %, respectively.
conclusionThere were specific features of the distribution of coronary arterial calcifications. It is important to be familiar with these features when deciding whether or not to perform subtraction CCTA.
