A randomized prospective study of single-port and four-port approaches for hysterectomy in terms of postoperative pain.
Trial report in Surgical endoscopy, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT01483417 (Multi-institution, Randomized Trial for Efficacy and Safety of Single Incision Laparoscopic Surgery), which is not on this map. Cited by 20 papers, 4 of them syntheses that pooled 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.
The trial behind it

Abstract
backgroundThis study aimed to compare single-port transumbilical total laparoscopic hysterectomy (SPLS-TLH) and four-port total laparoscopic hysterectomy (TLH) in terms of postoperative pain.
methodsThe study enrolled 68 patients who underwent TLH from October 2009 to March 2010 and randomly assigned them to one of two groups. Patient demographics, operative outcomes, and postoperative pain were prospectively examined.
resultsFour cases in the SPLS-TLH group were converted to other laparoscopic approaches. The two study groups did not differ in terms of patient demographics and surgical outcomes. Postoperative pain scores, measured using a visual analog scale, did not differ between the two groups. However, significantly higher total requests for analgesics were observed in the SPLS-TLH group (11.3 ± 4.1 vs. 7.7 ± 2.7; p < 0.001).
conclusionCompared with four-port TLH, SPLS-TLH is a feasible approach with comparable operative outcomes. However, reduction of postoperative pain is not evident with SPLS-TLH.
