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

backgroundLow serum sodium has been associated with unfavorable outcome in several cancers. The prognostic value of serum sodium in esophageal carcinoma (EC) remains unclear. This study aimed to investigate preoperative serum sodium in association with outcome and survival benefit of adjuvant therapy for patients with EC.

methodsPreoperative serum sodium and clinicopathological indexes were retrospectively analyzed in 2155 patients who underwent esophagectomy at Sichuan cancer hospital. Overall survival (OS) and disease-free survival (DFS) were analyzed by using Kaplan-Meier method and Cox regression. Benefit of adjuvant therapy was estimated by using Propensity Score Matching.

resultsThe incidence of hyponatremia and hypernatremia were 2% (43/2155) and 3.5% (76/2155) in treatment-naive patients. Both sodium disorders indicated unfavorable OS (hyponatremia, adjusted HR[95% CI] = 1.78[1.2-2.62]; hypernatremia, adjusted HR = 1.52[1.1-2.11]) and DFS (hyponatremia, adjusted HR[95% CI] = 1.52[1.03-2.23]; hypernatremia, adjusted HR = 1.45[1.06-1.99]). Decreased sodium concentrations within the normal range were associated with poor OS and DFS. Postoperative adjuvant therapy was associated with improved three-year OS (56.6 vs. 40%; adjusted HR = 0.55 [95% CI, 0.41-0.73]) and DFS (51.9 vs. 36.2%; adjusted HR = 0.63 [95% CI, 0.48-0.83]) versus surgery alone in patients with low serum sodium (Na < 139.6 mmol/liter), but not in other sodium subgroups. Meanwhile, serum sodium was inversely correlated with cell counts of leukocytes, neutrophils, monocytes and C-reactive protein levels.

conclusionsThese results suggested that low preoperative serum sodium is associated with poor outcome in EC patients, and may predict survival benefit of adjuvant therapy.
