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

Background: Prothrombin gene mutations can be associated with either a thrombotic or a bleeding risk. Genomic studies and coagulation workup can provide valuable information to better understand their clinical importance. Key Clinical Question: We describe the case of a woman with a duplication of the entire prothrombin gene. Clinical Approach: A 42-year-old woman presented for thrombophilia screening following a history of unprovoked arterial and superficial venous thrombotic episodes. Coagulation workup demonstrated a marked increase in prothrombin levels and Conclusion: The present case demonstrated duplication of the entire prothrombin gene, associated with a significant hypercoagulable risk, a finding not previously reported in the literature.
