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

objectivesTo assess the effect an ambulance pre-alert call for patients with suspected acute myocardial infarction (AMI) would have on door to needle (DTN) times.

methodsWe carried out back to back audits of DTN times following the initiation of the pre-alert calls.

participantsAll patients thrombolysed within the emergency department between July 2003 and April 2004 (inclusive). STATISTICAL ANALYSIS: Mean DTN times and time to ECG pre-change and post-change were compared using the Two sample t test. The Fisher's exact test was used to compare pre-change and post-change proportions of patients seen within guideline times.

resultsIn total, 73 patients were thrombolysed with 40 of these arriving by ambulance. Eighteen of these 40 were pre-change and 22 were post-change. Four patients were excluded. Fifty per cent of the pre-change group had a DTN time of <30 minutes compared with 91% of the post-change group (p = 0.005, Fisher's exact test). The phase one mean DTN time was found to be significantly greater than that for phase two (Two sample t test, p = 0.016; 95% CI 1.6 to 14.6).

conclusionsThere was a significant reduction in DTN times after the introduction of the pre-alert call.
