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

Objective: In this study, we aimed to investigate the ventilatory effect of plastic shields in a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection cluster site using the CO Methods: We experimentally investigated indoor air ventilation using the CO Results: Observations at several locations revealed extremely low air change rates (0.1/h) in the study site. Local infection clusters were observed several meters away from the door, the only means of ventilation in the office, indicating the negative effect of plastic sheet shielding. The thermo-fluid simulation showed that the plastic sheet blocked the airflow and trapped the exhaled air in each partition cell. Conclusion: Our results verify that opening windows and using fans to blow air out of the window, which led to a considerable improvement in air ventilation (10-28/h) in each partition cell, are suitable methods for lowering SARS-CoV-2 infection risk.
