Robot-assisted versus laparoscopic single-incision cholecystectomy: results of a randomized controlled trial.
Trial report in Surgical endoscopy, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to 2 registered trials, which are not on this map. Cited by 36 papers, 11 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.

Abstract
backgroundAlthough single-port laparoscopic cholecystectomy (SILC) is safe and effective, inherent surgeons' discomfort has prevented a large-scale adaptation of this technique. Recent advances in robotic technology suggest that da Vinci Single-Site™ cholecystectomy (dVSSC) may overcome this issue by reducing the stress load of the surgeon compared to SILC. However, evidence to objectively assess differences between the two approaches is lacking.
methods60 patients [36 women, 24 men (mean age 52 years)] with benign gallbladder disease were randomly assigned to dVSSC (n = 30) or SILC (n = 30) in this single-centre, single-blinded controlled trial. The primary endpoint was surgeon's stress load. Secondary endpoints included operating time, conversion rates, additional trocar placement, blood loss, length of hospital stay, procedure costs, health-related quality of life, cosmesis and complications. Data were collected preoperatively, during the hospital stay, and at 1 and 12 months' follow-up.
resultsThe dVSSC group showed a significant reduction of mental stress load of the surgeon compared to SILC [Subjective Mental Effort Questionnaire (SMEQ) score: median 25.0 (range 8-89) vs. 42.5 (range 13-110) points; p = 0.002] and a trend towards reduced physical stress load [Local Experienced Discomfort (LED) score: median 8 (range 2-27) vs. 12 (range 0-64) points; p = 0.088]. The length of hospital stay was longer in the SILC group [mean 3.06 (median 2; range 1-26) vs. 1.9 (median 2; range 1-4) days, p = 0.034] but overall hospital costs were higher for dVSSC [median 9734 (range 5775-16729) vs. 6900 (range 4156-99977) CHF; p = 0.001]. There were no differences in the rate of postoperative complications that required re-intervention (Dindo-Clavien grade ≥ IIIa; SILC n = 2 vs. dVSSC n = 0, p = 0.492) or other secondary endpoints.
conclusionsDa Vinci Single-Site™ cholecystectomy provides significant benefits over Single-Port Laparoscopic Cholecystectomy in terms of surgeon's stress load, matches the standards of the laparoscopic single-incision approach with regard to patients' outcomes but increases expenses.
