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
contextIn UK and French, but not World Health Organization (WHO), guidelines for combined hormonal contraception (CHC), family history of a venous thromboembolism (VTE) is a condition for which the theoretical risks usually outweigh the advantages of using CHC.
objectiveWe estimated the prevalence of inappropriate prescriptions of CHC according to several international guidelines and their impact on VTE.
designA single-center observational study.
settingHemostasis unit outpatient clinic (Paris, France). POPULATION: A total of 2088 French CHC users of childbearing age with a first documented VTE who were referred to our unit between 2000 and 2009.
methodsData were collected by a standardized questionnaire during a medical consultation. Family history of VTE was analyzed according to definitions from international recommendations (VTE before age 45 years, United Kingdom; before age 50 years, France). A CHC prescription was considered inappropriate for women with vascular contraindications and/or a family history of VTE. Cross-sectional analysis of the clinical and biological characteristics was performed.
main outcome measuresPrevalence of inappropriate prescription of CHC and potentially preventable events were estimated.
resultsAccording to the WHO, UK, or French guidelines, 8.8%, 18.9%, and 25.9%, respectively, of CHC prescriptions were considered inappropriate. Compliance with these guidelines could reduce the corresponding number of VTEs by 6.3%, 13.5%, and 18.5%, respectively. Characteristics of the women were similar.
conclusionOur results suggest inappropriate CHC prescriptions are prevalent among CHC users with first VTE. The appropriate way to take family history of VTE into account should be further clarified.
