1 · What the graph read from it

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.

2 · The registry

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

Background: Concurrent tuberculosis (TB) and COVID-19 increases the risk of mortality; however, most studies have focused primarily on short-term outcomes. We assessed the short and long-term impact of TB and SARS-CoV-2 coinfection on all-cause mortality. Methods: We conducted a retrospective nationwide cohort study in Chile, including adults diagnosed with active TB from January 1st, 2020, to December 31st, 2021, with follow-up until November 30th, 2022. SARS-CoV-2 coinfection was defined as occurring from 30 days before to six months after TB diagnosis. Short-term mortality was defined as death within 90 days of TB or TB/SARS-CoV-2 diagnosis, and long-term mortality as death occurring after 90 days. We used a time-dependent Cox survival analysis, adjusting for sociodemographic factors, SARS-CoV-2 vaccination, and relevant comorbidities including HIV, diabetes and Findings: The cohort included 3721 adults (median age: 47 years, interquartile range [IQR]: 32-61); of whom 63·4% were male, and 79·4% had pulmonary TB. The median follow-up was 586 days (IQR: 401-820), with 680 deaths (18·3%) recorded. A SARS-CoV-2 coinfection was identified in 393 individuals (10·5%); the mortality in this group was higher in short-term (≤90 days: 14·5% vs. 11·4%) and long-term (>90 days: 11·5% vs. 5·9%) compared to TB alone. Coinfection increased the risk of all-cause mortality during the entire follow-up (aHR [adjusted Hazard Ratio]: 2·8, 95% CI: 2·26-3·47), over three-fold in the short-term (aHR 3·4, 95% CI: 2·57-4·51) and nearly two-fold in the long-term (aHR: 1·72, 95% CI: 1·18-2·52). Excess mortality persisted beyond the first year (aHR: 2·04, 95% CI: 1·09-3·82). SARS-CoV-2 vaccination reduced mortality risk in the TB cohort by 35% (95% CI: 19-46%). Interpretation: Tuberculosis and SARS-CoV-2 coinfection was associated with significantly increased all-cause mortality in both the short and long-term, with elevated risk persisting beyond TB treatment completion. These findings highlight the need for continued post-treatment follow-up and prioritization of SARS-CoV-2 vaccination among individuals with TB. Funding: ANID-FONDECYT, Chile, and CONAHCYT, Mexico.
