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

backgroundAustralian guidelines recommend the CHA

methodsWe conducted a population-based cohort study using linked data from the New South Wales Admitted Patient Data Collection, the National Death Index and the Pharmaceutical Benefits Scheme databases. Oral anticoagulant-naïve patients with a first hospital admission for AF between July 2003 and January 2021 were included. Patients were followed for ≥12 months and classified into low-risk, intermediate-risk or high-risk categories for each score. 'Truly low-risk' was defined as annual ischaemic stroke incidence <0.9%. Predictive accuracy was assessed using the concordance-statistic.

resultsAmong 224 451 eligible patients, 3552 (1.6%) were hospitalised for ischaemic stroke within 12 months. The proportion labelled low-risk ranged from 2.0% (Modified-CHADS
