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

purposeThis study aimed to elucidate the impact of anatomic location of residual disease (RD) after initial cholecystectomy on survival following re-resection of incidental gallbladder cancer (IGBC).

methodsPatients with pT2 or pT3 gallbladder cancer (36 with IGBC and 171 with non-IGBC) who underwent resection were analyzed. Patients with IGBC were classified as follows according to the anatomic location of RD after initial cholecystectomy: no RD (group 1); RD in the gallbladder bed, stump of the cystic duct, and/or regional lymph nodes (group 2); and RD in the extrahepatic bile duct and/or distant sites (group 3).

resultsTiming of resection (IGBC vs. non-IGBC) did not affect survival in either multivariate or propensity score matching analysis. RD was found in 16 (44.4%) of the 36 patients with IGBC; R0 resection following re-resection was achieved in 32 patients (88.9%). Overall survival (OS) following re-resection was worse in group 3 (n = 7; 5-year OS, 14.3%) than in group 2 (n = 9; 5-year OS, 55.6%) (p = 0.035) or in group 1 (n = 20; 5-year OS, 88.7%) (p < 0.001). There was no survival difference between groups 1 and 2 (p = 0.256). Anatomic location of RD was independently associated with OS (group 2, HR 2.425, p = 0.223; group 3, HR 9.627, p = 0.024).

conclusionThe anatomic location of RD independently predicts survival following re-resection, which is effective for locoregional disease control in IGBC, similar to resection for non-IGBC. Not all patients with RD have poor survival following re-resection for IGBC.
