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

backgroundPersistent symptoms following severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection affect health-related quality of life (HRQoL) and impose a substantial burden on society. While previous studies showed that both coronavirus disease 2019 (COVID-19) patients and patients with acute respiratory symptoms but negative for SARS-CoV-2 experienced persistent symptoms, evidence comparing the long-term HRQoL of COVID-19 patients with test-negative controls for SARS-CoV-2 remains limited. This study aimed to compare symptoms and HRQoL using EQ-5D-5L in both acute and chronic phases between COVID-19 patients and test-negative controls for SARS-CoV-2 during the Omicron-predominant period in Japan.

methodsIndividuals aged ≥18 years tested for SARS-CoV-2 with COVID-19-like symptoms at a clinic in Tokyo, Japan, between January 2022 and January 2023, were invited an online survey. Individuals who tested positive and negative for SARS-CoV-2 were both included. Participants retrospectively recorded their physical and mental symptoms, and completed EQ-5D-5L questionnaires during the acute phase, and at months 1, 3, and 6, which were compared between COVID-19 patients and test-negative controls. Additionally, the mean EQ-5D-5L utility score was compared between male and female COVID-19 patients.

resultsA total of 302 COVID-19 patients and 77 test-negative controls were included (median age: 42 years; 41.2% male; 13.2% with underlying medical conditions). At month 3, 19.9% (60/302) of COVID-19 patients and 9.1% (7/77) of test-negative controls reported ongoing symptoms. Mental symptoms and fatigue persisted for over three months among COVID-19 patients. The mean EQ-5D-5L utility score during the acute phase for COVID-19 patients was 0.615 (95% confidence interval [CI]: 0.586-0.645), and 0.874 (95% CI: 0.826-0.921) for test-negative controls, with a mean difference of -0.258 (95% CI: -0.324 to -0.193). COVID-19 patients consistently exhibited lower EQ-5D-5L utility scores than controls for over six months post-infection. Female COVID-19 patients showed lower EQ-5D-5L utility scores compared to male patients throughout the period (acute phase mean difference: -0.091; 95% CI: -0.151 to -0.031).

conclusionsCOVID-19 patients experienced more symptoms three months post-testing compared to test-negative controls, with lower EQ-5D-5L utility scores persisting for over six months. Female COVID-19 patients exhibited lower EQ-5D-5L utility scores than their male counterparts throughout the period.
