Brain structures as potential mediators of the causal effect of COVID 19 on migraine risk.
Article in Scientific reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Migraine is a common neurological disorder observed after coronavirus disease 2019 (COVID 19) infection. However, the intricate relationship between COVID 19 and migraine, particularly the potential mediating role of brain imaging-derived phenotypes (BIPs), remains unclear. This study used linkage disequilibrium score regression (LDSC), a bidirectional two-sample Mendelian randomization (MR) approach, and two-step MR analysis to investigate potential causal links. The robustness of the MR findings was corroborated through generalized summary-data-based Mendelian randomization (GSMR) and MR-Steiger methods. The results of the LDSC analysis revealed that the genetic correlation coefficient between COVID 19 traits and migraine was 0.0277 for infection (P = 0.0051), 0.1690 for hospitalization (P = 0.0016), and 0.1147 for severity (P = 0.0330). The genetic correlation coefficients between COVID 19 infection, hospitalization, severity and migraine and migraine with aura (MA) were 0.2654 (P = 0.0012), 0.2065 (P = 0.0043), and 0.1537 (P = 0.0230), respectively. Two-sample MR analysis revealed a significant causal association of COVID 19 infection (odds ratio [OR] 1.2502, P = 0.0083; OR 1.4956, P = 0.0084), hospitalization (OR 1.0689, P = 0.0138; OR 1.0919, P = 0.0208), and severity (OR 1.0644, P = 0.0072; OR 1.0844, P = 0.0098) with increased risk of migraine and migraine with aura (MA). Cortical thickness (CT), total surface area (TSA), and fractional anisotropy (FA) were identified as BIP intermediaries in the risk trajectory from COVID 19 to migraine. The TSA exhibited a more pronounced mediating effect than did CT. This study revealed that genetically predicted COVID 19 is associated with an increased risk of migraine and MA, and BIPs act as potential mediators of these causal relationships, offering insights into the neurobiological underpinnings of migraine in the context of COVID 19.
