SCREENING OF ASYMPTOMATIC COVID-19 CASES FROM THE ASPECT OF VIRUS SPREAD.
Article in Acta clinica Croatica, 2024. 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
The COVID-19 pandemic has hit the entire world. While symptomatic patients can be taken out of the infection chain, asymptomatic cases are very important for the spread of SARS-CoV-2. We investigated the relationship between isolating asymptomatic COVID-19 cases with close contacts by identifying and breaking the infection chain. This study included 3 asymptomatic COVID-19 cases identified during screening and 25 close contacts as a result of filiation. Twenty-five people with close contact were classified into groups A (n=8), B (n=6) and C (n=11). On SARS-CoV-2 PCR tests performed in close contacts, all of them were negative on day 0, whereas two group C subjects were positive on day 7. On antibody test applied on day 28, six subjects were positive in group A, two subjects were positive in group B, and one subject was positive in group C. A statistically significant decrease was observed in the number of infected people in the group where asymptomatic cases were identified and removed (p=0.04). It was determined that asymptomatic COVID-19 cases who were not isolated from the community had a 5-fold increased risk of infection. Screening and identification of asymptomatic cases is also essential to augment the effectiveness of quarantine and isolation measures.
