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

It is a basic tenet of the sentinel lymph-node biopsy procedure that all positive sentinel lymph nodes will inevitably progress to palpable nodal recurrence if not removed. Comparison of survival is, therefore, considered permissible among patients with positive sentinel lymph nodes who undergo early lymphadenectomy with that among patients who have delayed lymphadenectomy for palpable regional node metastasis, providing that survival is calculated from the date of wide local excision of the primary tumor. Here, that fundamental assumption is contested and evidence is presented to show that a positive sentinel lymph node might have no adverse prognostic relevance in up to one-third of patients. Furthermore, in the same patients, progression to palpable nodal disease might not have occurred even if the positive sentinel node had not been removed. The term prognostic false-positivity is used to describe this phenomenon. Such patients are incorrectly up-staged, are given inaccurate prognostic information and can undergo unnecessary completion lymphadenectomy and unnecessary adjuvant therapy.
