Association between combined oral contraceptive prescription and cervical artery dissection: A retrospective cohort study.
Article in Thrombosis research, 2025. 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
backgroundTo date, research has identified positive associations between combined oral contraceptives (COCs) and adverse vascular events, however, evidence regarding the possible association with cervical artery dissection (CeAD) remains limited. We tested the hypothesis of a positive association between COCs and CeAD within one year following COC initiation compared to matched controls initiating intrauterine devices (IUDs), as measured by risk ratio (RR).
methodsWe queried de-identified United States health records data (TriNetX, Inc.) from 2014 to 2024 for females aged 15-50 years without previous cerebrovascular disease or CeAD, creating mutually exclusive cohorts initiating either COCs or IUDs. We used propensity matching to control for variables associated with CeAD. Our primary outcome included the RR for CeAD within one year follow-up. We secondarily explored cumulative CeAD incidence and RR of stroke, also examining outcomes for females with ≥2 COC prescriptions (COC2).
resultsAfter matching there were 214,020 patients per cohort (mean age 31 years). The incidence and risk of CeAD was greater among those prescribed COCs compared to matched controls with IUDs [95 % CI] (COCs: 0.016 %, IUDs: 0.008 %; RR 1.94 [1.10,3.43]; P = 0.0195). A similar association was observed for stroke (COCs: 0.106 %, IUDs: 0.057 %; RR = 1.86 [1.49,2.32]; P < 0.0001). The secondary COC2 analysis revealed similar findings.
conclusionsThe present findings suggest that females prescribed COCs have an increased risk of CeAD and stroke compared to matched controls using IUDs. These observations should be viewed as preliminary, require corroboration by other studies, and in isolation do not replace the broader clinical and shared decision-making regarding contraceptive use.
