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
Cross-reactive T cell immunity between common cold coronaviruses and SARS-CoV-2 may influence COVID-19 susceptibility. To identify cross-reactive CD8 T cell epitopes, we analyzed responses to 21 homologous SARS-CoV-2 replicase peptides in 177 people living with HIV (PLWH) on antiretroviral therapy, of which 133 did not have prior SARS-CoV-2 infection. Replicase peptides induced IFN-γ responses in 63% of the SARS-CoV-2-naïve individuals and in 73% of individuals with prior SARS-CoV-2-infection. We could define several cross-reactive epitopes, including the HLA-B∗35:03 restricted CoV-YL8, and characterized a CoV-YL8-specific T cell receptor cloned from a SARS-CoV-2 seronegative individual. Analysis of the association between HLA-I alleles and SARS-CoV-2 infections over a 16-months period revealed that in a cohort of 452 PLWH, HLA-B∗35:03 and C∗07 were underrepresented in the 55 persons with a history of SARS-CoV-2 infection while HLA-B∗35:01 and HLA-C∗04 were associated with a higher infection rate. Taken together, our study suggests an HLA-I-mediated effect of common cold coronaviruses on SARS-CoV-2 immunity.
