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

introductionMelanoma accounts for around 1% of all skin tumors yet is responsible for 80% of deaths related to skin cancer. Although adjuvant therapies improve survival, their effects on nevi remain unclear.

objectivesThis study aimed to investigate the dermoscopic and histopathological features of melanocytic nevi in melanoma patients receiving adjuvant systemic therapy.

methodsDermoscopic images of 1,299 melanocytic nevi from 25 melanoma patients undergoing adjuvant therapy (targeted therapy, immunotherapy, or IFN-α) were analyzed before and after treatment. The histopathological features of 129 excised nevi from 67 melanoma patients were compared between patients who received adjuvant therapy and those who did not.

resultsMelanoma patients on targeted therapy showed a greater reduction in global pigmentation and disappearance of the pigment network than those on IFN-α and immunotherapy (p=0.001 and P=0.017, respectively). IFN-α therapy was associated with more atypical pigment network changes than targeted therapy and immunotherapy (P=0.027). Histopathologically, structural atypia, cytological atypia, inflammation, and fibroplasia were more prevalent in excised nevi from patients receiving adjuvant therapy (P=0.003, P=0.004, P<0.001, P=0.020, respectively).

conclusionsAdjuvant systemic therapy induces dermoscopic and histopathological changes in melanocytic nevi. Clinicians and pathologists should carefully consider these alterations during melanoma follow-up to inform treatment decisions.
