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
backgroundIt is unclear how lung function may recover in patients with residual lung abnormalities (RLAs) following COVID-19 pneumonia. PURPOSE: To evaluate lung function trends over time in patients with RLAs following hospitalization due to COVID-19. STUDY TYPE: Prospective, multicenter longitudinal cohort study. POPULATION: Twenty-four participants hospitalized due to COVID-19 with RLAs identified on CT ≥ 3 months postdischarge (median [IQR] age 69 (15) years; 3 female) underwent at least one MRI at 6 months (n = 16), 1 year (n = 19), or 2 years (n = 14). FIELD STRENGTH/SEQUENCE: 1.5 T. Dynamic contrast enhanced (DCE) 3D spoiled gradient echo, ASSESSMENT: Pulmonary blood flow, volume, and mean transit time (MTT) were calculated from DCE MRI. The fraction of STATISTICAL TESTS: Changes in metrics with time and associations between metrics were assessed using mixed-effect linear regression. Correlations were tested using Spearman's correlation coefficient. Regional differences were assessed using a Friedman's test with a Bonferroni adjustment. p < 0.05 was considered significant.
resultsPulmonary blood flow and MTT improved significantly over time (MTT: 6 months, 15.3 (IQR, 2.0); 1 year, 15.6 (1.4); 2 years, 15.0 (5.3); pulmonary blood flow: 6 months, 75.4 (IQR, 22.0); 1 year, 83.2 (47.4); 2 years, 107.3 (51.1)). RBC:M z-score was low at all three visits (6 months, -2.85 (0.98); 1 year, -2.44 (1.34); 2 years, -2.60 (1.39)), with no improvement with time (p = 0.993). VDP and Lm DATA
conclusionImprovements in lung perfusion were measured; however, there was no corresponding enhancement in RBC:M. EVIDENCE LEVEL: Level 2. TECHNICAL EFFICACY: Stage 3.
