Clinical outcomes and lung ultrasound findings in COVID-19 follow up: Calm comes after the storm?
Observational study in Respiratory medicine and research, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled 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.
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
introductionThere is still an undiscovered territory about the sequelae and lung ultrasound (LUS) findings after SARS-CoV2 acute infection. This study aims to investigate the post-COVID period from a clinical, psychosocial, and radiological point of view, analyze LUS on COVID-19 follow-up and detect whether these outcomes are related to the patient situation.
methodsWe conducted an observational study on patients diagnosed with SARS-CoV2 pneumonia and admitted to the University Hospital of La Candelaria (Tenerife, Spain) from 1st March to 31st August 2020. We performed a descriptive analysis on post-COVID manifestations, LUS score, health-related quality of life measured through the Euroqol 5D-5L questionnaire, and lung function parameters on follow-up, and we compared these variables to the outcomes during the hospital admission.
results77 patients were included; the mean age was 57 years and the follow-up mean time from hospital discharge was 16 weeks. 87% of the cases had symptoms on follow-up, the most common was dyspnea (65%); these manifestations were more frequent in females (p = 0,015). 76,5% of the cases had lung aeration alteration in LUS on follow-up; lower PaO2/FiO2 and greater CRP and IL-6 levels on admission were related to LUS score ≥1.
conclusionsAlmost 90% of the patients had persistent symptoms after 16 weeks of hospital discharge due to COVID-19, the most common manifestation presented was dyspnea. Altered lung aeration pattern in LUS was observed on more than 70% of the patients on follow-up.
