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

rationaleGlyceryl trinitrate, a nitric oxide donor, is a candidate treatment for acute stroke; it lowers blood pressure, does not alter cerebral blood flow or platelet function and is neuroprotective in experimental stroke. The ongoing rapid intervention with glyceryl trinitrate in hypertensive stroke trial-2 trial aims to assess the safety and efficacy of paramedic-delivered glyceryl trinitrate in patients with ultra-acute stroke.

resultsThis paper describes the statistical analysis plan for the rapid intervention with glyceryl trinitrate in hypertensive stroke trial-2 trial and was developed prior to unblinding to treatment allocation. The statistical analysis plan includes details of methods for analyses and unpopulated tables and figures to be included in the primary and other secondary publications. DISCUSSION: Statistical analysis plan details what analyses will be done prior to unblinding to treatment allocation to avoid bias in the findings. Rapid intervention with glyceryl trinitrate in hypertensive stroke trial-2 trial will determine whether glyceryl trinitrate administered ultra-acutely can improve outcome after stroke. The rapid intervention with glyceryl trinitrate in hypertensive stroke trial-2 trial is registered as ISRCTN26986053.
