1 · What the graph read from 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.

2 · The registry

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

introductionWith the advancement of surgical technology, the opportunity to integrate novel surgical preparation is imperative to improve patient outcomes and enhance safety.

methodsPatient specific perfused kidney phantoms including the tumor, parenchyma, artery, vein, and calyx were fabricated using 3D-printing and hydrogel injection molding from scans of 25 patients scheduled for robotic partial-nephrectomy (RAPN). Models are validated for anatomical accuracy, mechanical, functional properties and surrounded by the other models of relevant anatomy in a body cast for a simulated surgical rehearsal. We investigated the impact of these preoperative rehearsals preceding complex RAPN by analyzing changes in surgeons' decisions following review of both axial-imaging and following rehearsal simulation. Predictive ability of these rehearsal platforms was compared to live surgery outcomes and trifecta of cases as an outcome was calculated.

results25 patients with complex renal tumors, average 9.8 nephrometry score and 4.9 cm mean tumor diameter were consented. Mean blood loss and WIT were 193.2 ml and 19.8 min. Two Clavien 2 complications were reported at 30-day postoperative. Trifecta was achieved in 17 (68%) of surgical cases. Surgeons' confidence in their ability to complete a partial nephrectomy and ability to predict WIT significantly increased from initial viewing the axial imaging to after the rehearsal. The correlation coefficient between the procedural clinical data collected during the rehearsals and live surgery were calculated.

conclusionThe application of this versatile method for creating authentic perfused kidney phantoms can result in increased confidence in surgical plan and thus improved surgical performance and outcomes.
