1 · What the graph read from 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.

2 · The registry

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 effectiveness of subcostal transversus abdominis plane block (TAPB) in laparoscopic gastric cancer surgery is unknown. We aimed to investigate its opioid-sparing and pain-relief effects in laparoscopic gastrectomy for gastric cancer.

methodOne hundred and twelve patients undergoing elective laparoscopic gastrectomy were randomised to the TAPB or control group. The TAPB group received ultrasound-guided bilateral subcostal TAPB at the end of surgery, while the control group did not. We investigated fentanyl consumption administered via intravenous patient-controlled analgesia and as a rescue analgesic, the numeric rating scale (NRS) pain scores at rest and during coughing, and the opioid-related side effects at 6, 12, 24, and 48 h postoperatively. The primary outcome was cumulative fentanyl consumption at 24 h postoperatively.

resultsThe study included 53 patients in each group. The cumulative fentanyl consumption 24 h postoperatively was significantly lower in the TAPB group than in the control group (median difference -170 mcg, P = 0.03, 95% CI -360 to -15 mcg). Subcostal TAPB also significantly reduced the resting NRS score at 48 h postoperatively (median difference -1, 95% CI -1 to 0, P = 0.01) and coughing NRS score at all time points (all median difference -1, 95% CI -2 to 0, P < 0.01, P  = 0.02, 0.01, and 0.01, respectively). However, it did not reduce the occurrence of opioid-related side effects, except the use of antiemetics during the first 6 h postoperatively (TAPB, 1.9% vs. Control, 15.1%, P = 0.03).

conclusionUltrasound-guided bilateral subcostal TAPB provides efficient postoperative analgesia with an opioid-sparing effect after laparoscopic gastrectomy.
