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

backgroundOncologic surgery for T1b-T3 gallbladder carcinoma (GBC) consists of gallbladder fossa resection or bisegmentectomy IVb/V with negative margins and portal/retropancreatic lymphadenectomy. Frequency of high quality oncologic surgery, factors associated with its use, and the ability of chemotherapy to rescue low-quality surgery (LQS) remain unknown.

methodsThe NCDB was queried for patients diagnosed with stage I-III (T1b-T3) GBC undergoing curative-intent surgery from 2004 to 2016. These patients were divided into two groups based on receiving high quality surgery (HQS) or not; HQS was defined as cholecystectomy with partial hepatectomy, lymph node harvest ≥ 6, and negative margins. Logistic regression and Kaplan-Meier survival analyses were performed.

resultsA total of 3796 patients met inclusion criteria; only 364 (9.6%) met HQS criteria, and 3432 (90.4%) did not achieve HQS and were deemed low-quality surgery (LQS). HQS was associated with improved median overall survival (55.1 vs. 25.5 months, P < .001). Adjuvant chemotherapy (AC) was not able to rescue LQS with poorer survival compared to HQS without AC (27.9 vs 55.1 months, P < .001). Factors associated with HQS included private insurance (OR 1.809, P < .001), higher income (OR 1.380, P = .038), urban/rural residence (vs metropolitan) (OR 1.641, P = .001), higher education (OR 1.342, P = .031), Medicaid expansion states (OR 1.405, P = .005), stage 3 GBC (OR 1.642, P = .020), and reresection (OR 2.685, P < .001). Factors associated with LQS included older age (OR 0.974, P < .001), comorbidities (OR 0.701, P = .004), and laparoscopic approach (0.579, P < .001). Facility type incrementally improved HQS rate (integrated cancer network vs. comprehensive community, 9.8% vs. 6.1%, OR 1.694, P = .003; academic/research center vs. integrated cancer network, 14.9% vs. 9.8%, OR 1.599, P = .003).

conclusionWhile HQS for GBC strongly improves survival, it is infrequently practiced. The newly identified factors that improve survival for GBC, such as centralization, open approach, and insurance coverage, are modifiable and, therefore, should be considered to achieve optimal outcomes.
