Predictive value of preoperative weight loss on survival of elderly patients undergoing surgery for esophageal squamous cell carcinoma.
Article in Translational cancer research, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled 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.
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 role of preoperative weight loss (PWL) has rarely been studied in elderly patients undergoing surgery for esophageal squamous cell carcinoma (ESCC). The aim of this study is to evaluate whether PWL is an important determinant of survival in elderly patients following surgery for ESCC.
methodsThis retrospective study included a total of 974 elderly patients (≥65 years) who underwent esophagectomy for ESCC at the West China Hospital, Sichuan University from August 2005 to April 2013. PWL was determined as the percentage weight loss during the 3 months before admission. Patients were divided into three groups according to the PWL, defined as normal (PWL =0), slight PWL (0< PWL <10%) and severe PWL (PWL ≥10%). Prognostic factors were evaluated by using univariate and multivariate analyses.
resultsPatients were categorized as normal (n=605, 62.11%), slight PWL (n=284, n=29.17%) and severe PWL (n=85, 8.73%). Compared with patients without PWL, both the patients with slight and severe PWL suffered from higher risk of tumor depth invasion (P=0.002 and P<0.001, respectively), lymph node metastasis (P=0.009 and P=0.004, respectively) and advanced stage (P=0.006 and P<0.001, respectively). Both patients with slight and severe PWL were significantly associated with worse overall survival compared with patients without PWL (P=0.036 and P<0.001, respectively). Multivariate analysis revealed severe PWL was an independent prognostic factor of overall survival [hazard ratio (HR) =1.534, 95% CI: 1.163-2.024] after correcting for sex, body mass index (BMI), T stage, N stage, grade, and adjuvant therapy.
conclusionsFor elderly patients undergoing surgery for ESCC, PWL provided prognostic value for depth of tumor invasion, lymph node metastasis and advanced stage. PWL ≥10% was an independent predictor of worse overall survival.
