Mortality in patients with giant cell arteritis in Spain: results from the ARTESER registry.
Article in Arthritis research & therapy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectivesTo compare mortality rates between GCA patients and the general population in Spain, and to identify associated factors influencing mortality.
methodsARTESER, a multicenter registry by the Spanish Society of Rheumatology, includes GCA patients from June 2013 to March 2019. Demographic, clinical, imaging, histological and mortality data were collected retrospectively. Only patients with at least one year of follow-up were included for analysis. The mortality rates were expressed as the number of deaths per 1000 person-years, with 95% confidence interval (CI) by sex and age group. Kaplan-Meier method was performed for survival analysis. The factors influencing mortality were analyzed using Cox regression model.
resultsA total of 1200 patients with GCA were analyzed, with a mean (SD) follow-up of 2.18 (1.53) years. The overall five-year cumulative mortality rate (95%CI) was 37.86 (31.75-43.96) per 1000 patients/year. The cumulative mortality rate was significantly higher in males than females (59.04vs29.06; p<0.001). The age- and sex-adjusted cumulative mortality rate was similar to the Spanish general population (19.75vs20.72;p=0.559). In the multivariate analysis, older age (HR 1.11, 95%CI 1.073-1.142) and male sex (HR 1.775, 95%CI 1.214-2.594) were associated with increased mortality. Headache (HR 0.55, 95%CI 0.362-0.843) and high hemoglobin levels (HR 0.85, 95%CI 0.744-0.970) were protective factors against death.
conclusionsThe overall five-year age- and sex-adjusted cumulative mortality rate in GCA is similar compared to the general population. Older age and male sex appear to be associated with an increased risk of mortality, whereas headache and high hemoglobin levels might serve as protective factors against death.
