1 · What the graph read from 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.

2 · The registry

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

As a spasm provocation test of acetylcholine (ACH), incremental dose up (20/50/100 μg) into the left coronary artery (LCA) is recommended in the guidelines established by Japanese Circulation Society. Recently, Ong et al. reported the ACOVA study which maximal ACH dose was 200 μg in the LCA. We compared the angiographic findings between ACH 100 μg and ACH 200 μg in the LCA and also examined the usefulness and safety of ACH 200 μg in Japanese patients without variant angina. As a spasm provocation test, we performed intracoronary injection of ACH 200 μg after ACH 100 μg in 88 patients (55 males, 68.4 ± 11.7 years old) including 59 ischemic heart disease (IHD) patients and 29 non-IHD patients. Positive spasm was defined as >99 % transient stenosis (focal spasm) or 90 % severe diffuse vasoconstriction (diffuse spasm). Positive spasm by ACH 200 μg was significantly higher than that by ACH 100 μg (36 pts: 40.9 % vs. 17 pts: 19.3 %, p < 0.01). Diffuse distal spasm on the left anterior descending artery was more recognized in ACH 200 μg than in ACH 100 μg (30.7 vs. 13.6 %, p < 0.01). In 29 rest angina patients, positive spasm by ACH 200 μg (19 pts) was significantly higher than that by ACH 100 μg (7 pts) (65.5 vs. 24.1 %, p < 0.01). No serious irreversible complications were found during ACH 200 μg. Administration of ACH 200 μg into the LCA was safe and useful. We may reexamine the maximal ACH dose into the LCA.
