Estimation of tuberculosis mortality burden in Spain: a review of the major data sources.
Article in ERJ open research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Introduction: In Spain, notifications of cases of tuberculosis (TB) are registered through the National Epidemiological Surveillance Network (RENAVE). The Minimum Basic Data Set (CMBD) provides information on hospital discharge and the National Statistics Institute (INE) draws on medical death certificates. This study aimed to describe TB mortality in Spain and to compare estimates across data sources, as well as with EU/EEA countries. Material and methods: A retrospective study of TB data between 2008 and 2021 was performed. Mortality rates (MRs) were calculated for the three databases as well as case fatality rates (CFRs) for TB location and HIV status using RENAVE data. Time trends were calculated and the mean MR and annual mean percentage change for Spain were compared with EU/EEA countries. Results: Between 2008 and 2021, 4127 TB deaths were reported to RENAVE, 3877 to INE and 4775 to CMBD. The MR was 0.62 per 100 000 inhabitants for RENAVE, 0.59 for INE and 0.72 for CMBD. A statistically significant downward annual trend was observed. Highest MRs across all databases were found in men and in those over 80 years old. CFR was higher for meningeal TB and for HIV patients with a risk ratio of 2.02 (95% CI 1.82-2.2; p<0.05). Conclusion: Although the TB MR in Spain has followed a downward annual trend, it is necessary to continue improving prevention, diagnosis and treatment. This will require comprehensive measurement, better knowledge and better use of all information to complement surveillance systems.
