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

Patients treated with TNF-α antagonists may develop psoriasis-like skin lesions. Clinical manifestations include palmoplantar, inverse, localized or generalized guttate, plaque-type, eczematous, and pustular lesions; deep inflammatory nodes; and nonscarring alopecia, often with overlapping reaction patterns. They are classified as paradoxical psoriasis and interpreted as an inflammatory reaction resulting from the disturbed maturation of plasmacytoid dendritic cells, with overproduction of type I interferons due to tumor necrosis factor α (TNF-α) inhibition. Management frequently necessitates discontinuation of therapy. Here, we review the clinical presentation of six patients who were initially diagnosed with paradoxical psoriasis during TNF-α blockade due to the development of corresponding skin lesions. Dermatologic examination revealed that the lesions were impetigo contagiosa, ecthyma, folliculitis decalvans, ostiofolliculitis, nummular microbial eczema, or abscessing furunculosis-all caused by
