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

backgroundSurgical treatment is still the most effective treatment for gallbladder cancer. For the patients with stage T1b and above, the current guidelines recommend the extended radical operation, and oncologic extended resection can benefit the survival of the patients. The laparoscopic approach is still in the early phase, and its safety and oncological outcomes are not well known.

objectiveTo evaluate the technical feasibility and oncological outcomes of laparoscopic surgery for oncologic extended resection of early-stage incidental gallbladder carcinoma.

resultsThis study included 18 male and 32 female patients. Twenty patients underwent laparoscopic oncologic extended resection and 30 patients underwent open oncologic extended resection. All of the patients had R0 resection. A laparoscopic approach was associated with less intraoperative blood loss (242 ± 108.5 vs 401 ± 130.3; p < 0.01) and shorter duration of postoperative hospital stay (6.2 ± 2.4 vs 8.6 ± 2.3; p < 0.01). There was no statistically significant difference between two groups for lymph nodes yield (5.4 ± 3.5 vs 5.8 ± 2.1; p > 0.05), incidence of lymphatic metastasis (15% vs 16.67%; p > 0.05), residual disease (20% vs 23.3%; p > 0.05), and postoperative morbidity (15% vs 20%; p > 0.05). During follow-up time of median 20.95 (12-29.5) months, no significant difference was found between the two groups for early tumor recurrence (10% vs 13.33%; p > 0.05) and disease-free survival (p > 0.05).

conclusionLaparoscopic surgery may offer similar intraoperative, perioperative, and short-term oncological outcomes as an open oncologic extended resection for incidental gallbladder carcinoma.
