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

backgroundTeledermatology (TD) has emerged as a critical way of delivering care remotely in the COVID-19 pandemic.

objectiveWe conducted a systematic review to assess how TD has been implemented worldwide.

methodsWe searched PubMed, Scopus, Embase, Web of Science, and Google Scholar for articles on the use of TD for patient care, written in English and published from December 1, 2019, to October 15, 2020.

resultsTwenty-seven studies were included, involving 16,981 patients. There was significant uptake of TD during the pandemic. Synchronous TD appeared to be more commonly implemented than asynchronous TD. Common ambulatory dermatoses such as acne or eczema were reported to be more amenable to TD assessment and management. TD also appeared to be useful for the diagnosis of cutaneous involvement of COVID-19 infection and follow-up of stable oncodermatology cases. LIMITATIONS: A pooled analysis of all relevant outcomes was not always possible due to the heterogeneity in the methodologies of included studies.

conclusionTD is a useful and convenient tool for the management of common ambulatory dermatoses in the COVID-19 pandemic.
