Limitation of Using Ultrasonography After Positive Sentinel Lymph Node Biopsy in a Patient with Melanoma in the Detection of Lymph Node Metastasis.

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
Recent studies have shown that complete lymph node dissection (CLND) performed immediately did not improve the overall survival in patients with sentinel lymph node (LN)-positive melanoma. According to these results, nodal observation with ultrasonography becomes standard. However, it still has some limitations for detection of metastatic LNs. A 74-year-old woman was diagnosed with acral lentiginous melanoma of her left sole. The sentinel LN was positive for metastasis, but she refused CLND. Sixteen months after operation, ultrasonography showed an abnormal LN in the inguinal region. There was no other abnormal LNs around the LN. We resected the abnormal LN. The resected LN was black in color, and the adjacent LN that showed normal appearance in ultrasonography was also black. A recent study showed only 6.6% sensitivity in preoperative ultrasonographic detection of metastatic melanoma in a LN. We should keep in mind the limitation of ultrasonography for detection of a metastatic LN.
