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

backgroundSystematic data on

methodsIn this single-center retrospective analysis, 21 patients with pathologically confirmed chordoma and prior treatment underwent

resultsMetastatic disease was identified in 11 of 21 patients (52.4%). Metastases were found in bone (7 patients), soft tissue (8 patients), and lung (5 patients). Site-specific metabolic patterns emerged: pulmonary metastases had lower FDG avidity (median SUVmax 2.3) correlated with size, whereas bone and soft-tissue avidity (SUVmax 3.8-3.9) was size-independent. Notably, in 4 out of 21 patients (19.0%), PET/CT detected metastases outside the field of view of conventional imaging. Interobserver agreement was perfect for metastatic status and excellent for total lesion counts. A case illustrated differential treatment response linked to baseline metabolic avidity.
