Minimally invasive esophagectomy: a propensity score-matched analysis of semiprone versus prone position.
Article in Surgical endoscopy, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 18 papers.
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 preferred surgical approach for esophageal cancer is a minimally invasive transthoracic esophagectomy with a two-field lymph node dissection. The thoracoscopic phase may be performed either in prone- or in left lateral decubitus (LLD) position. Prone positioning has been associated with better pulmonary outcomes compared to LLD positioning; however, conversion to a classic thoracotomy is more difficult. The semiprone position has been proposed as an alternative approach.
methodsA retrospective review of a prospectively maintained database (2008-2014) was performed to compare postoperative complications, surgical radicality, and lymph node yield between patients who underwent three-stage minimally invasive transthoracic esophagectomy in either the prone or semiprone position. Comparative analyses were conducted before and after propensity score matching.
resultsOne hundred and twenty-one patients were included. In total, 82 patients underwent minimally invasive esophagectomy (MIE) in semiprone position and 39 patients in prone position. After propensity score matching, both groups consisted of 39 patients. The operative time in the semiprone group was longer (368 vs. 225 min, P < 0.001) and in this group the lymph node yield was significantly higher (16 (range 6-80) vs. 13 (range 3-33), P = 0.019). There were no statistically significant differences regarding radical resections, postoperative complications, and hospital stay.
conclusionThe use of semiprone positioning in MIE is safe, feasible, and at least comparable to MIE in prone position in terms of oncological clearance and postoperative complications.
