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

backgroundPreoperative physiological assessments are crucial for optimizing clinical outcomes, especially those of elderly esophageal cancer (EC) patients who are generally frail and at the high risk of mortality.

methodsPatients who underwent surgery for EC between 2004 and 2018 were retrospectively reviewed. Patients were categorized into elderly (>70 years) or non-elderly (≤70 years) groups. Various physiological parameters including the Charlson Comorbidity Index (CCI), immunonutritional parameters and pulmonary functions were studied. Pulmonary functions included %vital capacity (VC) and forced expiratory volume in one second (FEV1.0) and FEV1.0%. The thresholds were set as the lowest quartile (100% for %VC and 2L for FEV1.0) in this cohort. Multivariate Cox hazards models were applied to determine independent predictors of non-EC-related deaths.

resultsIn total, 824 patients were included (elderly; n = 306, non-elderly; n = 518). Elderly patients had a significantly lower 5-year OS rate than non-elderly patients (53.3% vs. 57.2%, P = 0.03), mainly due to increased risk of death from non-EC related causes. In the elderly group, multivariate Cox hazards analysis identified 3 independent predictors of non-EC-related deaths; high CCI (HR 1.98, P=0.006), low %VC (HR 2.01, P = 0.004) and low FEV1.0 (HR 1.6, P=0.048). Elderly patients without risk factors had a significantly better 5-year OS rate (63.5%) than those with 1 (50.0%) or 2-3 (36.3%) risk factors (P <0.01). Deaths due to pulmonary disease rose significantly as the number of risk factors increased (P=0.03).

conclusionsThe severity of comorbidities and pulmonary function impairments are useful for predicting long-term outcomes, especially non-EC-related deaths, in elderly EC patients.
