Surgical Strategies for Bismuth Type I and II Hilar Cholangiocarcinoma: Impact on Long-Term Outcomes.
Article in Journal of gastrointestinal surgery : official journal of the Society for Surgery of the Alimentary Tract, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundThe surgical approach to treat Bismuth type I and II hilar cholangiocarcinoma (HCCA) has been a topic of debate. We sought to characterize whether bile duct resection (BDR) with or without concomitant hepatic resection (HR) was associated with R0 margin status, as well as define the impact of HR+BDR versus BDR alone on long-term survival.
methodsPatients who underwent curative-intent HR+BDR for HCCA between 2000 and 2014 were identified from a multi-institutional database. Perioperative and long-term outcomes were compared among patients who underwent BDR only, BDR+left hepatic resection (LHR), and BDR+right hepatic resection (RHR) for Bismuth type I and II HCCA.
resultsAmong 257 patients with HCCA, 61 (23.7%) patients had a Bismuth type I (n=25, 41.0%) or II (n=36, 59.0%) lesion. The incidence of R0 resection after BDR only was the same as among patients after LHR and RHR (BDR 70.0% vs. BDR+LHR 71.4% vs. BDR+RHR 76.5%, p=0.891). In contrast, severe complications were more likely after LHR and RHR than BDR only (BDR 21.4% vs. BDR+LHR 60.0% and BDR+RHR 50.0%, p=0.041). Overall (median: BDR 20.9 vs. BDR+LHR 23.2 and BDR+RHR 25.0 months, p=0.213) and recurrence-free (median: BDR 13.4 vs. BDR+LHR 15.3 and BDR+RHR 25.0, p= 0.109) survival were comparable. On multivariable analysis, while CA19-9>37.0U/ml (Ref. CA19-9≤37.0U/ml, HR 3.2, 95% CI 1.1-9.4, p=0.035) and AJCC T3-T4 disease (Ref. T1-T2, HR 4.6, 95% CI 1.5-13.7, p=0.007) were associated with long-term survival, surgical approach was not (BDR+LHR: HR 1.0, 95% CI 0.5-2.2, p=0.937; BDR+RHR: HR 0.6, 95% CI 0.3-1.3, p=0.197).
conclusionR0 resection, overall survival, and recurrence-free survival were comparable among well-selected patients who had BDR versus BDR+HR for Bismuth type I and II HCCA.
