Laparoscopic-Assisted Transversus Abdominis Plane (TAP) Block Versus Port-Site Infiltration with Local Anesthetics in Bariatric Surgery: a Double-Blind Randomized Controlled Trial.
Trial report in Obesity surgery, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06383234 (REduced Pain After Bariatric Surgery - Sleeve Gastrectomy), which is not on this map. Cited by 8 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.

Abstract
backgroundThe transversus abdominis plane (TAP) block has shown great potential usefulness in the management of postoperative pain; however, there is lacking evidence regarding its use in bariatric surgery. This randomized double-blind trial was aimed at comparing the effectiveness of the TAP block and port-site infiltration (PSI) in patients undergoing bariatric surgery.
methodsWe included patients ≥ 18 years old undergoing bariatric surgery. From July 2020 to July 2021, all eligible patients were randomized to receive either laparoscopic-assisted TAP block or PSI. Demographic and clinical data were collected and analyzed.
resultsDuring the study period, we included 113 patients. Fifty-one were allocated to the TAP block group and 62 to the PSI group. The mean age was 47.9 ± 11.2 years, 88 (77.9%) patients were female, and mean BMI was 40.5 ± 5.9 kg/m
conclusionsPatients undergoing bariatric surgery and receiving either the TAP block or the PSI had similar postoperative pain, nausea, length of stay, and satisfaction. As PSI is technically easier and more reproducible, it might be the first choice for postoperative multimodal analgesia in bariatric surgery.
