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

introductionRadiation therapy (RT), commonly used in cancer management, has been considered as one of the potential treatments for COVID-19 pneumonia. Here, we present the results of the pilot trial evaluating low-dose whole-lung irradiation (LD-WLI) in patients with COVID-19 pneumonia.

methodsTen patients with moderate COVID-19 pneumonia were treated with LD-WLI in a single fraction of 0.5 or 1.0 Gy along with the national protocol. The primary endpoint was an improvement in Spo

resultsThe median age was 75 years (80% male). Five, 1, and 4 patients received single-dose 0.5 Gy, two-dose 0.5 Gy, and single-dose 1.0 Gy LD-WLI, respectively. The mean improvement in Spo

conclusionLD-WLI with a single fraction of 0.5 Gy or 1 Gy is feasible. A randomized trial with patients who do not receive radiation is required to assess the efficacy of LD-WLI for COVID-19.
