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

Halo naevi are considered benign. They occur in children and adolescents. Eruptive multiple halo naevi are infrequently seen in adults. The first patient in this case series had previously had melanoma. Positron emission tomography-computed tomography (PET-CT) showed a papillary thyroid carcinoma. Subsequent adult patients underwent an examination programme similar to melanoma patients with unknown primary, including PET scanning. Sixteen patients were followed over a 6-year period. In total there were 2 papillary thyroid cancers, 1 neuroendocrine lung tumour, 1 patient had had lung metastases from a thin melanoma 7 years previously, 3 patients had primary cutaneous melanoma (1 had had halo naevi since excision of 2 melanomas 15 years previously) and 1 had melanoma metastasis with unknown primary. The incidence of melanoma was 955 times higher than expected (standardized incidence rate). The benefits of PET scanning must be validated in a controlled trial prior to implementation into clinical practice.
