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

This paper applies the DCC-FIGARCH model to investigate the role of Bitcoin as a hedge and safe haven for Islamic stock markets in comparison with gold. We use daily data for the period January 2010-May 2020, which covers the recent COVID-19 pandemic. Empirical results show that the dynamic correlation between Bitcoin and Islamic stock markets is low and usually negative during major economic and political events suggesting that Bitcoin qualifies as a safe haven against Islamic stock markets downturns. Extending our analysis to portfolio management, findings reveal that the diversification benefits of Bitcoin are most times stable and increase significantly during turbulent periods. Thereby, adding Bitcoin in a portfolio of Islamic stocks reduce the risk of portfolio. Finally, as regards the COVID-19 outbreak period, we find that the hedging strategy involving Bitcoin leads to a higher cost during the crisis. These results provide substantial recommendations for Islamic investors and portfolio managers.
