Metachronous splenic metastasis from squamous cell carcinoma of the anus.

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
A woman in her 70s with a history of metastatic squamous cell carcinoma (SCC) of the anus in systemic remission presented with a new splenic metastasis on surveillance CT imaging consistent with the primary site of the anus as confirmed by histology. The patient consented to surgical management via laparoscopic splenectomy, which was facilitated by a combination of laparoscopic and hand-assist ports. Mobilisation of the spleen revealed local tumour invasion into the diaphragm, requiring resection and resulting in capnothorax, which was appropriately repaired. Final pathology showed a well-circumscribed 7.9×6.8×5.2 cm mass exhibiting microscopic morphology and nuclear markers consistent with poorly-differentiated SCC of the anus, confirming metastatic disease. Splenic metastases are a rare finding that may require surgical management. Splenectomy can be feasibly managed using minimally invasive techniques, such as laparoscopy, with or without hand assistance.
