1 · What the graph read from it

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.

2 · The registry

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

Coronavirus disease 2019 (COVID-19) was rapidly expanded worldwide within a short period. Its relationship with chronic comorbidities is still unclear. We aimed to determine the effects of chronic comorbidities on clinical outcomes of patients with and without COVID-19. This was an analysis of 65,535 patients with suspicion of viral respiratory disease (38,324 SARS-CoV-2 positive and 27,211 SARS-CoV-2 negative) from January 01 to May 12, 2020 using the national administrative healthcare open data of Mexico. SARS-CoV-2 infection was confirmed by reverse-transcriptase-polymerase-chain-reaction. General characteristics and chronic comorbidities were explored. Clinical outcomes of interest were hospital admission, pneumonia, intensive care unit admission, endotracheal intubation and mortality. Prevalence of chronic comorbidities was 49.4%. Multivariate logistic regression analysis showed that the effect of age, male sex, bronchial asthma, diabetes mellitus and chronic kidney disease on clinical outcomes was similar for both SARS-CoV-2 positive and negative patients. Adverse clinical outcomes were associated with the time from symptoms onset to medical contact, chronic obstructive pulmonary disease, hypertension and obesity in SARS-CoV-2 positive patients, but with cardiovascular disease in SARS-CoV-2 negative patients (p value < 0.01 for all comparisons). Chronic comorbidities are commonly found in patients with suspicion of viral respiratory disease. The knowledge of the impact of comorbidities on adverse clinical outcomes can better define those COVID-19 patients at higher risk. The different impact of the specific type of chronic comorbidity on clinical outcomes in patients with and without SARS-CoV-2 infection requires further researches. These findings need confirmation using other data sources.
