Prevalence of Long COVID in
Article in Journal of clinical tuberculosis and other mycobacterial diseases, 2026. 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
Objectives: Long COVID (LC), i.e. the persistence of new or worsening symptoms for 3 months after Severe Acute Respiratory Syndrome of Coronavirus 2 (SARS-CoV-2) infection, is an emerging global health burden. The prevalence of LC remains poorly characterized in low- and middle-income countries (LMICs), where other respiratory diseases, like tuberculosis (TB), are prevalent. We aimed to address this gap in Methods: We recruited people with TB (n = 36) and their asymptomatic household contacts (n = 63) in Peru. We collected clinical data using a questionnaire adapted from a United States-based study of LC. Participants were recruited within 2 years of SARS-CoV-2 diagnosis. Results: In Peru, 41% participants reported LC symptoms. The most common LC symptoms were neurological (e.g., headache) and musculoskeletal (e.g., back pain). We did not detect an association between TB disease or Conclusions: LC prevalence in Peru aligns with global trends, underscoring significant health burdens. Those with LC reported high levels of musculoskeletal and neurological symptoms, highlighting the need for long-term follow-up and larger studies in different geographic settings to dissect the impact of TB comorbidity on LC.
