Umbilical Nodule in a Patient With a History of Colon Cancer.
Article in Cureus, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 Sister Mary Joseph nodule (SMJN) is a rare cutaneous manifestation of metastatic intra-abdominal or pelvic malignancy and typically indicates advanced disease. We report the case of a 48-year-old female patient who presented to our dermatology clinic with a three-month history of a painless, skin-colored umbilical mass with intermittent foul-smelling serosanguinous drainage. Her medical history was noteworthy for metastatic adenocarcinoma of the colon diagnosed five years earlier, initially treated with subtotal colectomy and adjuvant chemotherapy, followed by recurrence with ovarian involvement consistent with a Krukenberg tumor and subsequent immunotherapy-induced remission. Physical examination and histopathologic findings were consistent with the diagnosis of an SMJN of colorectal origin, supported by immunohistochemical staining confirming metastatic adenocarcinoma of the colon. This case highlights the diagnostic value of a dermatologic evaluation and a timely biopsy in identifying SMJN and guiding appropriate staging and management.
