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
aimTo evaluate changes of right ventricular (RV) parameters in follow-up examinations after corrected tetralogy of Fallot (TOF) by cardiac magnetic resonance (CMR).
methodsCMR was performed twice within 4 years in 45 patients using a 1.5 T scanner. RV-volumes and pulmonary-regurgitant-fractions (PRF) were calculated from standard cine-sequences and flow-sensitive gradient-echo images, respectively. Patients were divided into two groups depending on the post-operative (po) interval (group 1 ≤5 years po; group 2 >5 years po) and subgroups depending on type of surgery (transannular vs. non-transannular). Patient groups were compared among each other and differences between 1st and 2nd CMR were assessed. Furthermore, patients were compared with 25 healthy volunteers.
resultsCompared with controls RV-size was increased (group 1: p = 0.007; group 2: p < 0.001) and RV function decreased (group 1: p = 0.02; group 2: p < 0.001) in po TOF-patients. PRF was higher in group 2 compared with group 1 (p = 0.04) and significant changes of PRF between 1st and 2nd CMR were found in group 2 (p < 0.01), but not in group 1 (p = 0.29). Compared with the non-transannular subgroup, PRF (p < 0.001) and RV end-diastolic-volume index (RV-EDVI) (p = 0.03) were significantly higher in patients with a transannular patch, EDVI increased between 1st and 2nd CMR. After correction, no significant changes of RV myocardial mass index (RV-MMI) were found.
conclusionAfter correction of TOF, RV-size, RV-muscle mass (RV-MM) was increased and ejection fraction decreased in "early" follow-up already. Whereas these parameters can remain stable over a long time period, the PRF significantly increased in "late" follow-up dependent on the po interval. Overall, transannular patching went along with higher PRF and bigger RV-size as well as a greater dynamic of these parameters in the time course, which makes this subgroup highly in need of regular follow-up examinations for the optimal timing of re-interventions. In contrast, the increased RV-MM demonstrated no regression po.
