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

backgroundPostoperative chylothorax is a serious complication following esophagectomy. The efficacy of thoracic duct ligation (TDL) for chylothorax prevention is controversial. This study aimed to evaluate the impact of TDL on chylothorax prevention, postoperative biochemical changes, and overall survival (OS) in esophageal cancer patients.

methodsWe conducted a retrospective cohort study including 991 patients who underwent esophagectomy for esophageal cancer(May 2017-May 2020), stratified into TDL (n = 286) and non-TDL (n = 705) groups. Propensity score matching (PSM) was employed to minimize selection bias(252 pairs matched). Primary endpoints included chylothorax incidence, postoperative biochemical markers, and 5-year OS.

resultsTDL did not reduce the incidence of chylothorax (1.2% vs. 1.2%, P = 1.000). It significantly decreased serum protein levels (postoperative ALB 31.8 vs. 32.5 g/L, P= 0.047), while liver enzymes and bilirubin remained unaffected. No survival benefit was observed (5-year OS 42% vs. 45%, P = 0.49).

conclusionAfter excluding invasion cases and balancing measurable confounders, TDL was not associated with a lower incidence of chylothorax or improved long-term survival.
