A randomized phase II study of the clinical effects of ultrasonically activated coagulating shears (Harmonic scalpel) in open gastrectomy for gastric cancer.
Trial report in Surgery today, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeThe Harmonic Ace ultrasonic scalpel has been popular in abdominal surgery; however, only a few clinical studies have evaluated the efficacy of this device in radical open gastrectomy for gastric cancer.
methodsThe present study was designed as a multicenter, prospective, randomized, controlled trial. Patients with resectable gastric cancer were randomly assigned to gastrectomy using the Harmonic scalpel or conventional monopolar electrosurgery.
resultsA total of 248 patients were enrolled, and 123 patients were included in the Harmonic group and 114 patients were included in the conventional group. The demographics of the patients were well balanced between the groups. There was no significant difference in the length of the operation from skin incision to resection of the gastric specimen (141 ± 36 min in the Harmonic group vs. 147 ± 13 min in the conventional group; p = 0.276) nor in the amount of blood lost (365 ± 293 vs. 336 ± 272 mL; p = 0.434). There was also no significant difference in the incidence of surgical complications or the post-surgical hospital stay between the groups.
conclusionThe Harmonic scalpel procedure was not superior to the conventional monopolar electrosurgery with regard to reducing the length of the operation, blood loss, postoperative complications, or postoperative hospital stay in radical open gastrectomy.
