Psychiatric symptoms of long COVID among adults: observational case-control study in Johannesburg, South Africa.
Article in BJPsych open, 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
backgroundGrowing research has underscored the elevated prevalence and burden of psychiatric morbidity among adults living with long COVID. The severity of acute SARS-CoV-2 infection may predict the prevalence and severity of psychiatric symptoms in long COVID. Although Global South countries have faced among the highest incidence rates and burden of COVID-19, little is known about the psychiatric symptoms of long COVID in these regions, especially in Sub-Saharan Africa.
aimsThis study aimed to (a) compare the prevalence of long-term psychiatric symptoms between acute COVID-19 infection groups, (b) estimate the associations between COVID-19 severity and long-term psychiatric symptoms, (c) determine the association between long COVID symptoms and psychiatric symptoms, and (d) test the potential mediating effect of long COVID symptoms in the association between acute COVID-19 infection and psychiatric symptoms.
methodThis case-control study took place in Johannesburg, South Africa, between August 2022 and July 2023. A total of 360 adults were categorised into one of four case groups based on initial COVID-19 symptoms: asymptomatic, symptomatic, admitted to hospital and vaccinated controls.
resultsPrevalence rates of post-traumatic stress disorder (21.1%) and somatic symptoms (22.9%) were elevated. Individuals with symptomatic COVID-19 exhibited the greatest psychiatric morbidity out of all groups, exhibiting the highest levels of depression, suicidality, anxiety, post-traumatic stress disorder, bipolar disorder and somatisation. Acute COVID-19 severity was associated with worse symptoms of depression, somatisation and physical fatigue. Severity of long COVID symptoms was directly associated with psychiatric sequelae.
conclusionsThese results call attention to the long-term psychiatric sequelae of SARS-CoV-2 infection and early identification and management of emerging psychiatric symptoms in high-risk COVID-19 survivors.
