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

Perineural spread (PNS) from cutaneous squamous cell carcinoma (cSCC) to the skull base is increasingly recognised as a route of cancer spread. Management historically involved definitive radiotherapy to treat PNS at the skull base. In the endemic region with modern magnetic resonance neurogram (MRN) and skull base surgical expertise, the outcome has improved over the years. With the advent of immunotherapy, the outcome may be maintained while preserving critical organs in the head and neck region. We conducted a critical review of the literature to establish the treatment outcomes and pattern of failure as practice evolved. Furthermore, we described our skull base surgical and radiotherapy management guideline and outlined the emerging paradigm shift in the immunotherapy era.
