Effect of preoperative computed tomography parameters and obesity on surgical outcomes of laparoendoscopic single-site adrenalectomy.
Article in Surgical endoscopy, 2020. 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
backgroundThe aims of the present study were to (1) analyse preoperative computed tomography (CT) parameters, (2) investigate whether obesity and CT parameters affect surgical outcomes in patients undergoing LESS lateral retroperitoneal adrenalectomy, and (3) further establish the optimal cutoff point of CT parameters for tolerable operating time.
methodsBetween January 2010 and August 2016, patients who underwent LESS adrenalectomy through the retroperitoneal approach in our hospitals were included. Patients' demographic data, preoperatively measured CT parameters (the depth and horizontal width to the adrenal gland in the axial view of abdominal CT, the vertical height in the coronal view of CT, and the angle of the depth and horizontal width), and intraoperative (operative time and blood loss) and postoperative (hospital stay and complications) parameters were retrospectively reviewed. Linear regression was performed to determine factors that potentially affect surgical outcomes.
resultsIn 116 patients, depth was the only CT parameter associated with surgical outcomes. Large depth (P = 0.005; 95% CI 1.739-9.256) and high BMI (P = 0.012; 95% CI 0.357-2.851) were factors significantly associated with longer operative time. The area under the ROC curve for the depth was 0.69 (P = 0.002), and the cutoff point 10.48 cm may be the tolerable operating time.
conclusionsOur results suggest a depth limit of 10.48 cm for the optimal prediction of operating time less than 90 min; although obese patients and deeper adrenal glands had longer operative time, LESS adrenalectomy could be performed in the obese patients without increased blood loss, prolonged hospital stay, or increased pain.
