HIV and risk of COVID-19 death: a population cohort study from the Western Cape Province, South Africa.
Article in medRxiv : the preprint server for health sciences, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundThe effect of HIV co-infection on COVID-19 outcomes in sub-Saharan Africa is unknown.
methodsWe conducted a population cohort study using linked data from adults attending public sector health facilities in the Western Cape, South Africa. We used Cox-proportional hazards models adjusted for age, sex, location and comorbidities to examine the association between HIV and COVID-19 death among (i) public sector 'active patients' (at least 1 health visit in the 3 years before March 2020), (ii) laboratory-diagnosed COVID-19 cases and (iii) hospitalized COVID-19 cases. COVID-19 was diagnosed with SARS-CoV-2 PCR tests. We calculated the standardized mortality ratio (SMR) for COVID-19 comparing HIV positive vs. negative adults using modelled population estimates.
resultsAmong 3,460,932 public sector patients (16% HIV positive), 22,308 were diagnosed with COVID-19, of whom 625 died. In adjusted analysis, HIV increased risk of COVID-19 mortality (adjusted hazard ratio [aHR]:2.14; 95% confidence interval [CI]:1.70; 2.70), with similar risks across strata of viral load and immunosuppression. increased HIV-associated risk of COVID-19 death remained when restricting to COVID-19 cases (aHR:1.70; 95%CI:132; 2.18) or hospitalized cases (aHR:1.45; 95%CI:1.14; 1.84). Current and previous tuberculosis also increased COVID-19 mortality risk (aHR [95%CI]:2.70 [1.81; 4.04] and 1.51 [1.18; 1.93] respectively). The SMR for COVID-19 death associated with HIV was 2.39 (95% CI:1.96; 2.86); population attributable fraction 8.5% (95%CI:6.1; 11.1).
conclusionHIV was associated with a doubling of COVID-19 mortality risk. While our findings may over-estimate the HIV-associated risk COVID-19 death due to residual confounding, people with HIV should be considered a high-risk group for COVID-19 management.
