The Role of Log Odds of Positive Lymph Nodes in Predicting the Survival after Resection for Ampullary Adenocarcinoma.

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
Lymph node metastasis is a important factor on survival in ampullary adenocarcinoma. Log odds of positive lymph nodes (LODDS) is a novel prognostic indicator on lymph node status. We aimed to evaluate the prognostic impact of LODDS for the patients with ampullary adenocarcinoma who underwent R0 pancreaticoduodenectomy. The study includes 42 patients.. LODDS was calculated as "log (number of metastatic lymph nodes+0.5)/(number of total harvested nodes - metastatic lymph nodes+0.5)". LODDS subgroups were created based on their LODDS value: LODDS1(LODDS≤ - 1.5), LODDS2(-1.5 < LODDS≤ - 1.0), LODDS3(-1.0 < LODDS≤ - 0.5), LODDS4(LODDS> - 0.5). The mean survival time was 72.7 ± 7.82 months. Survival rates for 1, 3 and 5 years were 93%, 65% and 45%, respectively. The mean LODDS value was -1.0466 ± 0.51. LODDS subgroups show strong correlation with Overall Survival(OS). The mean survival were 114.8, 81.8, 56.6 and 25.6 months in LODDS subgroups 1, 2, 3 and 4, respectively (Log-rank; p = 0.002), in addition LOODS values shows correlation with perineural invasion and micro vascular invasion (p = 0.015 and p = 0.001 respectively). Findings in our patient group support the hypothesis that LODDS subgroups correlate with OS, and that value of LODDS has considerable role in prediction of OS as well.
