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

introductionOff-label, under-, and overdosed direct oral anticoagulants (DOACs) are commonly prescribed to patients with atrial fibrillation (AF), but real-world evidence on their effectiveness and safety is limited.

methodsMEDLINE, Embase, and Cochrane Library databases were systematically searched from 01 July 2020 to 28 February 2022 to update a previous systematic review with the same search strategy from the inception to 30 June 2020. Eligible studies were those that reported effectiveness (stroke/systemic embolism and myocardial infarction) or safety (gastrointestinal or major bleeding and death) outcomes of off-label doses of DOACs compared to on-label doses in AF patients. A random-effects meta-analysis was performed to estimate the pooled hazard ratio (HR) and 95% confidence interval (CI). Subgroup analyses were performed by specific DOACs and geographic regions.

resultsTwenty-two studies were included. Off-label, underdosed DOACs, compared to on-label doses, were not associated with an increased risk of stroke (HR 1.03, 95%CI: 0.88-1.17) but were associated with an increased risk of death (HR 1.26, 95%CI: 1.09-1.43). However, risk varied depending on the active ingredient. No other safety outcomes were associated with underdosed DOACs. No significant differences were observed by geographic regions. Compared to on-label DOACs, overdosing increased the risk of stroke (HR 1.17, 95%CI: 1.04-1.31), major bleeding (HR 1.18, 95%CI: 1.05-1.31), and death (HR 1.19, 95%CI: 1.03-1.35). Risk varied between geographical regions.

conclusionsOff-label underdoses, compared to on-label dosing of DOACs, did not increase the risk of stroke but did increase overall mortality. Overdosed DOACs, compared to on-label doses, were associated with an increased risk of stroke, major bleeding, and death. Future studies must examine these associations, focusing on specific active ingredients and geographic settings.
