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 examines the impact of corporate diversification on stock returns during and after the market crash caused by Covid-19. Using regression and survival analyses, we find that diversified firms experience worse returns and slower improvement in stock prices than focused firms. However, diversified firms trading at diversification premium have better returns and faster recovery compared to those trading at discount. Our findings presented here can be relevant to academics and industry professionals in their understanding of the role of corporate diversification in difficult times.
