Long-term mortality and cause of death in people with tuberculosis compared with matched controls with influenza or non-typhoid salmonellosis in Australia: a retrospective cohort study.

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: Tuberculosis (TB) patients are thought to experience excess long-term morbidity and mortality. However, the long-term mortality of people with TB has not been compared with other common infections to assess their overall and disease-specific causes of death. Methods: All people diagnosed with TB between 2000 and 2015 in New South Wales, Australia, were matched by age, sex and year of infection to notified cases of influenza or non-typhoid salmonellosis. Patients were linked to the Australian mortality register to assess date and cause of death, up until the end of 2022. The comparative mortality ratio (CMR) for each cohort was calculated and Kaplan-Meier survival curves constructed. The standardised mortality rate (SMR) was estimated using national mortality data. Results: The CMR of 7386 people with past TB was marginally increased (1.16 with 95% CI 1.10 to 1.22) compared with non-typhoid salmonellosis but reduced compared with influenza (0.88 with 95% CI 0.84 to 0.93). Most deaths occurred within 10 years of the notified infection. For TB patients, 1162 of 1331 people (87.3%) died in the 10 years after TB diagnosis. Risk factors for long-term mortality among TB patients included age over 40 years, male sex, sputum smear-positive and intracranial disease. Respiratory causes of death, including chronic obstructive pulmonary disease, lung cancer and pneumonia, were increased for TB patients, while influenza patients suffered more cardiovascular deaths. The SMR for TB patients (compared with the Australian general population) was increased by 18.7 times for infectious causes of death, 2.8 times for respiratory causes and 1.4 times for cancer-related mortality. Conclusions: Despite successful treatment, people with TB often experience post-TB sequelae and increased long-term mortality, with increased risk of respiratory causes of death. This highlights the need for appropriate post-TB respiratory follow-up, particularly in the first 10 years after TB diagnosis.
