Log odds of positive lymph nodes predicts survival in metaplastic breast cancer based on SEER analysis.

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
purposeTo investigate, for the first time, the association between LODDS and survival outcomes in MBC patients after surgery.
methodsThis retrospective analysis included 1,776 patients diagnosed with MBC recorded during 2010-2017 through the Surveillance, Epidemiology, and End Results (SEER) database. The optimal LODDS cutoff was determined. using maximally selected rank statistics, with patients subsequently categorized into low (L1) and high (L2) groups of LODDS. Cox models, Kaplan-Meier, and restricted cubic splines analyzed OS and BCSS.
resultsAfter adjusting for demographic and tumor-related characteristics, LODDS remained significantly associated with OS and BCSS, both as a continuous and categorical variable. In adjusted model, the L2 group exhibited mortality increases of 25% for all causes (HR: 1.25, 95% confidence interval [CI]: 1.06-1.48, P = 0.009) and 29% for breast cancer-specific causes (HR: 1.29, 95% CI: 1.05-1.58, P = 0.015) compared to the L1 group. The Log-rank analysis (P = 0.003) confirmed superior survival outcomes in the L1 group compared to L2 group. RCS analysis revealed a nonlinear U-shaped correlation between LODDS and OS (P < 0.001), while a linear correlation was observed between LODDS and BCSS (P = 0.443).
conclusionThese findings provide the first evidence that LODDS has a significant non-linear association with OS and a significant linear association with BCSS in patients with MBC after surgery. Higher LODDS values were associated with elevated risks of all-cause mortality and breast cancer-specific mortality.
