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

backgroundThis study evaluated our new strategy for treating suspected T2 gallbladder carcinoma (GBC) using a laparoscopic approach.

methodsWe examined 19 patients with suspected T2 GBC who were treated laparoscopically (LS group) between December 2007 and December 2013; these patients were compared with 14 patients who underwent open surgery (OS group). Laparoscopic staging was initially performed to exclude factors making the patients ineligible for curative resection. Intraoperative pathological examination of the surgical margin of the cystic duct was performed prior to laparoscopic gallbladder bed resection, and pathological examination was again performed to confirm the presence of carcinoma and the depth of tumor invasion. Surgery was completed when the pathological findings indicated that the patient was cancer free. Lymph node dissection was performed according to the depth of tumor invasion.

resultsNone of the patients required conversion to laparotomy. For three patients with benign lesions, only gallbladder bed resection was required. Additional regional lymph node dissection was performed in 16 patients in the LS group. The mean operative time (309 vs. 324 min, p = 0.755) and mean number of dissected lymph nodes (12.6 vs. 10.2, p = 0.361) were not significantly different between the LS and OS groups. The intraoperative blood loss was significantly lower (104 vs. 584 mL, p = 0.002) and the postoperative hospital stay was significantly shorter (9.1 vs. 21.6 days, p = 0.002) for LS patients than for those in the OS group. In the LS group, one patient developed postoperative pneumonia, but all patients survived without recurrence after a mean follow-up of 37 months.

conclusionOur strategy for suspected T2 gallbladder GBC is safe and useful, avoids unnecessary procedures, and is associated with similar oncologic outcomes as the open method.
