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

backgroundWhile laparoscopic transabdominal or retroperitoneal adrenalectomy is standard care for adrenal tumors, benefits of robotic adrenalectomy (RA) are yet unclear. We evaluated the costs (including disposables), outcomes as well as the learning curve of robotic and laparoscopic adrenalectomy (LA) in a specialized center.

methodsIn retrospective analysis of our prospective database (ethical approval number 88/11) 263 LA were compared to 27 RA in the study period between 2018 and 2023. A propensity score match analysis was used to exclude possible confounders. Furthermore, the learning curve of RA was investigated.

resultsIntraoperative Riva Rocci (RR) fluctuations (> 160mmHg, < 90 mmHg), early complications (within 30 days) and intraoperative blood loss were comparable in both groups. However, length of stay was decreased following robotic adrenalectomy (3.50d ± 1.81d compared to 4.61d ± 2.75d; p = 0.04). Due to this, overall costs of RA were lower compared to LA even if cost for disposables were slightly higher in the robotic group. An analysis of the learning curve of robotic adrenalectomy revealed that learning curve is completed after 5- 6th procedure.

conclusionsTaken together our study supports the fact that RA is as secure and feasible as LA. Furthermore, it might provide advantages due to shorter length of stay, a short learning curve and similar costs compared to LA.
