Longitudinal assessment of physiological and mental health changes following acute COVID-19 in Uganda.
Article in Communications health, 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: Recovery following acute COVID-19 varies widely, yet early recovery patterns remain understudied in Africa. Given the high burden of post-infection morbidity in resource-limited settings, there is a need to characterize recovery trajectories and identify those at risk for delayed recovery. Methods: We enrolled 151 adults between July 2021 and July 2022 with confirmed SARS-CoV-2 infection from healthcare facilities in Uganda and followed them for 12 weeks. Outcomes included pulmonary function, exercise capacity, symptom burden, and mental health, and were analyzed descriptively and using mixed-effects models. Results: Participants with severe acute COVID-19 had the greatest impairments during recovery. At 12 weeks, forced expiratory volume in 1 second (FEV1), diffusing capacity of the lungs for carbon monoxide (DLCO), and six-minute walk distance remained lower in severe versus mild cases (mean (SD): 98.45 (22.22) vs 105.26 (12.29); 78.99 (18.83) vs 107.72 (20.44); 409.28 (71.18) vs 506.82 (70.87)), consistent with adjusted models showing lower FEV1 (β = -13.10, 95% CI: -24.13, -2.07), DLCO (β = -40.75, 95% CI: -53.84, -27.66), and six-minute walk distance (β = -95.87, 95% CI: -136.66, -55.08). Continued COVID-19 and mental health symptoms were reported across all groups; mild cases had worse mental health scores (23.19 (12.65) vs 16.95 (13.98)), while severe cases had a broader range of persistent symptoms, including fatigue, breathlessness, and cognitive complaints. Conclusions: In this longitudinal study in Uganda, COVID-19 was associated with persistent physiological and psychosocial impacts, particularly among those with severe illness. Initial severity may help identify individuals at risk for delayed recovery and guide targeted post-COVID care in resource-limited settings.
