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

Background: The Shamblin classification is the standard for predicting carotid body tumor (CBT) surgical outcomes; however, its subjective nature limits prognostic accuracy. This study compared the predictive value of preoperative tumor volume vs Shamblin classification for perioperative morbidity and mortality in CBT resection at a tertiary center. Methods: A single-center retrospective cohort study analyzed data from 24 consecutive CBT resections performed at an Academic Hospital (January 2015-2025). Tumor volumes were calculated from preoperative contrast-enhanced computed tomography using three-dimensional volumetric reconstruction. Spearman's rank correlation, Mann-Whitney Results: The cohort comprised 19 women (79%) and 5 men, with a mean age of 52 years. Ten tumors (42%) were Shamblin II, and 14 (58%) were Shamblin III; no Shamblin I tumors were identified. Median tumor volume was significantly larger in Shamblin III (63 cm Conclusions: Tumor volume correlated more strongly and more reproducibly with surgical outcomes than the Shamblin classification and may serve as an objective, continuous adjunct for risk stratification; the two systems are best regarded as complementary. A volume threshold of >73 cm
