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

backgroundChilblains have emerged as a cutaneous manifestation following coronavirus disease 2019 vaccination. While there are many case reports on chilblain-like lesions, documentation from tropical countries remains limited. In this context, we report a case detailing chilblain-like lesions associated with coronavirus disease 2019 vaccination in Thailand. CASE PRESENTATION: A 35-year-old Thai female patient presented with several painful, red papules on the fingers and toes 9 days after receiving the mRNA-1273 vaccination. Skin biopsy was performed, and the results were consistent with chilblains. Laboratory workup revealed positive result for lupus anticoagulant. The rash completely resolved without any treatment but reappeared following the second vaccine dose.

conclusionChilblain-like lesion following coronavirus disease 2019 vaccination is frequently observed in temperate countries, with few reports from tropical areas. The presence of lupus anticoagulant may contribute to the development of chilblains after coronavirus disease 2019 vaccination.
