Quality of life of people with and without respiratory complications in post-COVID-19 syndrome: a retrospective study.
Observational study in Revista brasileira de enfermagem, 2026. 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
objectivesto assess and compare the quality of life (QoL) of people with and without respiratory complications resulting from post-COVID-19 syndrome.
methodsa retrospective, comparative, and analytical observational study, with a quantitative approach and non-probabilistic convenience sampling, conducted with 300 people residing in Ceará, Maranhão, or Pernambuco, distributed into case group (n=100/with respiratory complications) and control group (n=200/without respiratory complications). For data collection (2021-2022), the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) and the St George's Respiratory Questionnaire (SGRQ) were used. Student's t-test, ANOVA, and Pearson correlation were performed (p<0.05).
resultsthe case group presented lower scores in all SF-36 domains (p<0.05), indicating worse QoL. In the SGRQ, symptoms, activity, and impacts showed greater impairment (p<0.001). An inverse linear correlation was observed between SF-36 and SGRQ scores.
conclusionspeople with post-COVID-19 respiratory complications presented worse QoL, highlighting the relevance of multidisciplinary follow-up in respiratory rehabilitation for improving QoL.
