Recovery of lung function during the first year after COVID-19: a systematic review and meta-analysis.
Synthesis in European respiratory review : an official journal of the European Respiratory Society, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundSeveral studies have reported lung function impairment following COVID-19. Less is known about the subsequent recovery. RESEARCH QUESTION: What is the recovery in lung function after COVID-19 during the first year after infection?
methodsWe conducted a systematic review and meta-analysis of studies that monitored individuals' lung function from the time of infection to at least 1 year after infection. Primary outcomes were change in percent predicted forced expiratory volumes in 1 s (FEV
resultsWe included 23 studies (n=3347 participants). 20 (86.9%) studies had their first follow-up 3 months after infection and 21 (91.3%) had their second follow-up 12 months after infection. The MDs between the second and first follow-up visits of FEV
interpretationRecovery in lung function was evident during the first year after COVID-19, with the largest improvement in patients with the most severe infection. Further follow-up and large-scale studies are warranted to establish recovery trajectories of COVID-19 and other respiratory infections to identify patient subgroups needing additional follow-up to ascertain modifiable factors influencing pulmonary recovery.
