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

backgroundSensitive troponin (Tn) assays have been developed for the evaluation of patients with suspected acute coronary syndrome (ACS). We sought to compare the performance of a commercially available sensitive Tn I (sTnI) and precommercial highly sTnI (hsTnI) method to conventional Tn (cTn) assays.

methodsAmong patients with acute chest pain but normal cTn in the emergency department of 6 centers, sTnI and hsTnI were measured at baseline, 2 and 4 hours after presentation. Diagnostic accuracy of sTnI and hsTnI relative to cTn for diagnosis during index hospitalization as well as their associations with coronary artery disease in patients randomized to coronary computed tomographic angiography (CTA) was assessed.

resultsOverall, 322 patients were enrolled, of whom 161 had a CTA; 28 had ACS (8.7%), including 21 with unstable angina pectoris (UAP). Both sTnI and hsTnI values at baseline and second draw had significantly higher sensitivity for ACS and UAP than cTn and had significantly greater area under the receiver operator characteristic curve than cTn at first and second draws. Compared with cTn, 29% of ACS cases previously categorized as UAP were reclassified to acute myocardial infarction with sTnI or hsTnI. An hsTnI below limit of detection had 100% negative predictive value for ACS or significant coronary artery stenosis in those randomized to CTA.

conclusionsIn patients with acute chest discomfort, use of sTnI and hsTnI methods led to significant improvement in the early diagnostic accuracy for ACS, reclassifying one-third of UAP to myocardial infarction. Very low values for hsTnI excluded underlying coronary artery disease.
