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

objectiveCorona Virus Disease-2019 (COVID-19) has been among the major infectious events of the century. In today's literature where COVID-19 and host factor effects are frequently examined, we aimed to examine another factor: Circadian Clock Protein PERIOD 3 (PER3). There is a significant correlation between PER3 gene polymorphism and circadian rhythm disturbances and immune system dysregulation.

methodsIn our study, we recruited 200 patients diagnosed with COVID-19 in our hospital between April-June 2020, and 100 volunteers without known comorbidities to create a healthy control group. After comparing the initial gene polymorphisms of the patients with healthy controls, three separate clinical subgroups were formed. Gene polymorphism distribution and statistical significance were examined in the formed patient groups.

resultsNo significant difference was found between the patient group and the healthy controls (P>0.05, for all). When patients were divided into two separate clinical subgroups as exitus/alive according to their last condition during their 28-day follow-up, the 4R/5R genotype was significantly more common in patients with a mortal course (P=0.007). The PER3 4R/5R genotype was found at a significantly higher rate in the group of patients with the need for intensive care (P=0.034).

conclusionThe 4R/5R genotype may be associated with the need for intensive care and mortality in COVID-19 patients. These important results will be a guide for future studies.
