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

A strong link between schizophrenia and a higher mortality rate from SARS-CoV-2 infections has been reported for schizophrenia patients, with a mortality odds ratio (OR) of 2.67 compared to normal patients, after adjustment of the OR for age, sex, race and extra risk factors. In addition, an extensive number of papers have reported a very strong link between schizophrenia and Toxoplasma gondii infections. A meta-analysis of 38 studies of links between schizophrenia and T. gondii antibody seroprevalence resulting from previous infections indicated that the likelihood of T. gondii infection in schizophrenia patients was 2.7 times higher than the general population. In other words, the meta-analysis indicated that schizophrenia patients had an odds ratio of 2.7 of T. gondii infection compared to the general population. This indicates that compared to the general population, schizophrenia patients have virtually the same odds ratio for having a T. gondii infection and for mortality from a COVID-19 infection. This suggests that T. gondii infections, directly or indirectly, have a relationship with higher mortality in COVID-19 patients having schizophrenia. This conclusion would also apply to the general population.
