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.
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: Chondrosarcoma is the second most common bone malignancy. Chondrosarcoma is considered a surgical disease, and the role of surgical margin is important since local recurrence is known to decrease survival. The aim of this study was to investigate the timing of local recurrence and the size of local recurrence in post local recurrence survival in chondrosarcoma. Methods: We reviewed data from one international tertiary sarcoma hospital. Between 1990 and 2022, 911 patients with chondrosarcoma of the pelvis and extremities were identified and 161 (18 %) had a local recurrence. Competing risk analysis was used to identify the timing and size of local recurrence in post local recurrence survival in different grades. Results: Increasing size of local recurrence was a statistically significant negative factor in grade 2 chondrosarcoma patients. The timing of local recurrence was not significant for post local recurrence survival. Only 7 % of the local recurrences in high grade tumours were detected after five years after index surgery. Conclusion: In this study we have shown that the size of local recurrence emerges as a significant factor in grade 2 tumours. Timing of local recurrence does not significantly predict the post local recurrence survival. Moreover, only 7 % of local recurrences are detected after five years in high grade tumours. Therefore, we recommend that active surveillance efforts be particularly focused on grade 2 chondrosarcomas during the initial five years after index surgery.
