Impact of heparin-aspirin therapy in patients with recurrent pregnancy loss characterized by thrombophilia resistant to low-dose aspirin therapy: A retrospective study.
Article in Reproductive medicine and biology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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.
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
Purpose: Heparin and aspirin (HA) therapy is used for antiphospholipid syndrome (APS)-associated recurrent pregnancy loss (RPL). Low-dose aspirin (LDA) is recommended for thrombophilic predispositions, such as antiphospholipid antibodies that do not completely meet the Sydney classification criteria for APS, protein S deficiency, factor XII deficiency and increased platelet aggregation. However, no established strategy exists for cases where LDA is ineffective. Therefore, this study aimed to identify the characteristics of RPL cases unresponsive to LDA and to determine whether HA is more effective than LDA in such cases. Methods: A total of 913 LDA-treated pregnancies were categorized into live births and miscarriages, and their characteristics were retrospectively analyzed. Results: The live birth rates following one, two, or three or more LDA therapies were 78.5%, 61.5% and 16.7%, respectively. Live birth rates were significantly lower when lupus anticoagulant (LAC) aPTT was positive but did not qualify as obstetric APS following LDA therapy (birth rates: 33.3%, Conclusions: HA therapy is recommended over repeated LDA treatment, particularly when LAC aPTT is positive but does not qualify as obstetric APS.
