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

purposeTo compare the clinical utility of preoperative psoas muscle index (PMI) and skeletal muscle index (SMI) cutoff stratification for predicting postoperative pulmonary complications (PPCs) and survival after esophagectomy.

methodsThis single-center retrospective study included 334 patients who underwent esophagectomy for thoracic esophageal cancer. Preoperative SMI and PMI were measured on CT images at the L3 level and classified using established cutoff values. Associations with PPCs were examined using multivariable logistic regression. The 5-year overall survival (OS) and recurrence-free survival (RFS) rates were evaluated.

resultsPPCs occurred in 110 patients in the study. The low-PMI group had significantly higher rates of PPCs and pneumonia than the no low-PMI group, whereas no significant differences were observed between the SMI-based groups. In a multivariable analysis, a low PMI was independently associated with PPCs (OR 2.17, 95% CI 1.16-4.07; p = 0.02), but a low SMI was not. The low-PMI group showed worse 5-year OS and RFS in unadjusted analyses, whereas SMI was not associated with these outcomes. In Cox regression analyses adjusted for other prognostic factors, the association between a low PMI and long-term outcomes was attenuated.

conclusionsThe preoperative PMI was more strongly associated with PPCs after esophagectomy than SMI. Although unadjusted analyses indicated an association, a low-PMI did not independently predict worse long-term outcomes in the adjusted analyses.
