Considering "Trifecta" as a Single Outcome when Comparing Robotic With Open Partial Nephrectomy: A Mathematical Model of Volume Conservation and Systematic Review.

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
BACKGROUND/
aimTrifecta represents a composite outcome reflecting the quality level of treatment in nephron sparing surgery. However, there is substantial heterogeneity concerning the criteria required for its fulfilment. The present study aimed to highlight the potential of a unified view for the different definitions of trifecta when comparing robotic and open approaches in partial nephrectomy. MATERIALS AND
methodsA systematic literature search was carried out for all relevant comparative studies published until April 2022. Trifecta definitions were clustered according to two criteria for postoperative renal function reduction. The first set as an upper limit the 10% decrease in the estimated glomerular filtration rate, while the second set as an upper limit 25 min of ischemia. To mathematically investigate the point of intersection between the above two groups, a suitable model of volume conservation equations was formulated.
resultsA total of 11 studies were investigated for their methodological features and grouped accordingly. The ischemic zone volume surrounding the tumor resection site emerged as the central parameter connecting the two main definitions. Specifically, for patients with solitary renal masses, a given change in the value of one parameter resulted in a fixed change in the value of the other.
conclusionThe two main definitions of the "trifecta outcome" extracted from the international literature represent the two sides of the same coin. Thus, trifecta achievement rates could be utilized by future studies as aggregate data to yield a quantitative estimate of the comparative effect between robotic and open approaches in partial nephrectomy procedures.
