Causes of hospitalization among people living with HIV in a tertiary-care hospital in Bogotá, Colombia, 2018-2024.
Article in PloS one, 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
BACKGROUND AND
objectiveDespite expanded access to antiretroviral therapy (ART), people living with HIV (PLWH) continue to experience high hospitalization rates, particularly in low- and middle-income countries. This study aimed to describe the causes of hospitalization in a cohort of PLWH treated at a high-complexity referral center in Bogotá, Colombia, and to assess variations across the pre-pandemic, pandemic, and post-pandemic periods of COVID-19. METHODOLOGY: We conducted a retrospective cohort study including hospitalization episodes among adults with confirmed HIV infection between 2018 and 2024. Clinical characteristics, causes of hospitalization, and outcomes were compared across the epidemiological periods related to the COVID-19 pandemic.
resultsA total of 872 hospitalization episodes corresponding to 584 patients were analyzed. The median age was 34 years, and 89.1% were men. Although 68.7% of patients had a history of ART use, 54.8% were admitted with detectable viral load. Non-AIDS-defining causes predominated across all periods (61.8%), with a progressive increase from the pre-pandemic to the post-pandemic period (55.3%, 63.1%, and 70.1%, respectively). A sustained increase in hospitalizations due to mental health disorders was observed over time (4.3%, 4.6%, and 7.8%). Among AIDS-defining conditions, tuberculosis (15.8%) and Pneumocystis jirovecii pneumonia (14.9%) were the most frequent. Hospitalizations due to opportunistic infections were associated with longer length of stay (median 14 vs. 6 days; p < 0.001) and higher 30-day mortality (8.6% vs. 2.6%; p < 0.001) compared with non-AIDS-defining hospitalizations, with a proportional increase in events attributable to tuberculosis and Kaposi sarcoma.
conclusionsAn epidemiological transition towards non-AIDS-defining causes of hospitalization is evident, comparable to patterns observed in high-income countries; however, a substantial burden of tuberculosis, Kaposi sarcoma, and late HIV diagnosis persists, likely reflecting ongoing structural gaps in HIV care. Following the COVID-19 pandemic, an increase in hospitalizations related to mental health disorders was observed. Taken together, these findings highlight the urgent need to strengthen early diagnosis, active case finding, and tuberculosis prevention, as well as to enhance the implementation of comprehensive care models that improve retention in care for PLWH in low- and middle-income countries.
