Robotic versus laparoscopic minimally invasive inguinal hernia repair: randomized clinical trial (the ROGER trial).
Trial report in The British journal of surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05216276 (Robotic Versus Conventional Minimal-invasive Inguinal Hernia Repair - a Prospective, Randomized and Blinded Clinical Trial), which is not on this map. Cited by 6 papers, 2 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
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.

Abstract
backgroundSuperiority of robotic inguinal hernia repair compared with a laparoscopic minimally invasive approach remains unproven. The aim of this study was to evaluate postoperative pain after laparoscopic totally extraperitoneal repair (TEP) compared with robotic transabdominal preperitoneal repair (rTAPP).
methodsThis was a prospective, patient- and investigator-blinded, two-group, single-centre RCT conducted at a tertiary Swiss healthcare institution including 182 patients undergoing elective primary inguinal hernia repair. Patients were randomized 1 : 1 and stratified according to BMI and unilateral or bilateral hernia to either TEP or rTAPP. Surgery took place between March 2022 and November 2024. The primary endpoint was postoperative pain while coughing 24 h after surgery. Surgical workload (assessed using the National Aeronautics and Space Administration (NASA) Task Load Index (TLX)) was also recorded.
resultsIn total, 91 patients (93% male, mean(s.d.) age of 56.8(15.2) years, mean(s.d.) BMI of 24.8(3) kg/m2, and 22% with bilateral hernias) were randomized to TEP and 91 patients (95% male, mean(s.d.) age of 55.1(14.5) years, mean(s.d.) BMI of 24.6(2.9) kg/m2, and 21% with bilateral hernias) were randomized to rTAPP. Primary outcome data were available for 90 TEP patients and 88 rTAPP patients. The median postoperative pain while coughing on a numeric rating scale 24 h after surgery was 5 (interquartile range (i.q.r.) 2-7) after TEP and 4 (i.q.r. 2-7) after rTAPP (P = 0.431, Cohen's d = 0.12). The mean(s.d.) operating time for unilateral hernias was 64.2(19.2) min for TEP and 80.3(20.9) min for rTAPP (P < 0.001). Ten (11%) postoperative complications occured after TEP and nine (10%) after rTAPP (P > 0.999). The mean(s.d.) NASA raw TLX score was 34.0(17.2) after TEP and 18.4(10.7) after rTAPP (P < 0.001).
conclusionrTAPP demonstrated no superiority over TEP regarding postoperative pain and complication rates. rTAPP was associated with a reduced surgeon workload at the expense of a longer operating time. REGISTRATION NUMBER: NCT05216276 (http://www.clinicaltrials.gov).
