Right ventricular outlet tract reconstruction for tetralogy of Fallot: systematic review and network meta-analysis.
Article in Interdisciplinary cardiovascular and thoracic surgery, 2024. 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
objectivesConcerns persist regarding pulmonary regurgitation after transannular patch repair (TAP) for tetralogy of Fallot. Despite the introduction of various architectural preservation techniques, the optimal strategy remains controversial. Our goal was to compare different right ventricular outlet tract reconstruction techniques.
methodsPubMed, EMBASE and Cochrane Central were searched through March 2024 to identify comparative studies on right ventricular outlet tract reconstruction techniques (PROSPERO ID: CRD42024519404). The primary outcome was mid-term pulmonary regurgitation, with secondary outcomes including postoperative mortality, postoperative pulmonary regurgitation, length of intensive care unit stays, postoperative right ventricular outlet tract pressure gradient and mid-term mortality. We performed a network meta-analysis to compare outcomes among TAP, valve-repairing (VR), TAP with neo-valve creation (TAPN) and valve-sparing (VS).
resultsTwo randomized controlled studies and 32 observational studies were identified with 8890 patients. TAP carried a higher risk of mid-term pulmonary regurgitation compared to TAPN [hazard ratio, 0.53; 95% confidence interval (CI) (0.33; 0.85)] and VS [hazard ratio, 0.27; 95% CI (0.19; 0.39)], with no significant difference compared to VR. VS was also associated with reduced postoperative mortality compared to TAP [risk ratio, 0.31; 95% CI (0.18; 0.56)], in addition to reduced ventilation time. TAP also carried an increased risk of postoperative pulmonary regurgitation compared to the other groups. The groups were comparable in terms of length of intensive care unit stay, right ventricular outlet tract pressure gradient and mid-term mortality.
conclusionsVR was associated with a reduced risk of postoperative pulmonary regurgitation, whereas TAPN was associated with reduced risks of both postoperative and mid-term pulmonary regurgitation.
