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

BACKGROUND AND

aimLymph node metastasis is a major prognostic factor for perihilar cholangiocarcinoma (PHC). However, prognostic significance of extent of node dissection, lymph node ratio (LNR), and number and location of positive nodes remain unclear. We aimed to evaluate whether node status, LNR, or number or location of positive nodes are independent factors for staging in PHC and to determine the minimum requirements for node examination.

methodsThe Surveillance, Epidemiology, and End Results database was used to identify 1116 resected PHCs from 1998 to 2008. The correlation between nodal status and survival was analyzed retrospectively.

resultsLymph node metastasis occurred in 43.4% patients and was an independent predictor for overall survival and cancer-specific survival. No survival benefit was observed for an increasing number of node retrieval in node-positive patients. However, in node-negative patients, ≥13 node dissection was of more survival benefit than 3 ≤ total lymph node count (TLNC) ≤ 12 and TLNC < 3 (5-year overall survival: 52.8% vs 39.7% vs 26.3%, P = 0.001; 5-year cancer-specific survival: 60.6% vs 46.3% vs 30.0%, P = 0.001). No difference in survival between patients with regional and distant node involvement was found. Survival for patients with greater than three positive nodes was significantly worse than that for those with three or less (relative ratio: 1.466, P = 0.001). And patients with LNR > 0.27 also had unfavorable prognosis (relative ratio: 1.376, P = 0.001).

conclusionsWe determined that to adequately assess nodal status of this life-threatening disease, 13 or more nodes retrieval should be considered. Number of positive nodes and LNR rather than location of metastatic nodes may be defined as parameters for staging of PHC.
