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

objectiveTo assess whether a novel 'direct access pathway' (DAP) for the management of high-risk non-ST-elevation acute coronary syndromes (NSTEACS) is safe, results in 'shorter time to intervention and shorter admission times'. This pathway was developed locally to enable London Ambulance Service to rapidly transfer suspected high-risk NSTEACS from the community to our regional heart attack centre for consideration of early angiography.

methodsThis is a retrospective case-control analysis of 289 patients comparing patients with high-risk NSTEACS admitted via DAP with age-matched controls from the standard pan-London high-risk ACS pathway (PLP) and the conventional pathway (CP). The primary end point of the study was time from admission to coronary angiography/intervention. Secondary end point was total length of hospital stay.

resultsOver a period of 43 months, 101 patients were admitted by DAP, 109 matched patients by PLP and 79 matched patients through CP. Median times from admission to coronary angiography for DAP, PLP and CP were 2.8 (1.5-9), 16.6 (6-50) and 60 (33-116) hours, respectively (p<0.001). Median length of hospital stay for DAP and PLP was similar at 3.0 (2.0-5.0) days in comparison to 5 (3-7) days for CP (p<0.001).

conclusionsDAP resulted in a significant reduction in time to angiography for patients with high-risk NSTEACS when compared to existing pathways.
