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

introductionThere is a growing literature on the 'crowding-out' effects of tobacco expenditure, particularly in Low-to-Middle Income Countries (LMICs). However, there is no published study investigating these effects in the context of Ghana, a country where tobacco consumption is expected to increase in the future. This study aims to investigate whether tobacco influences expenditure patterns within Ghanaian households.

methodsWe estimate a demand system of quadratic conditional Engel curves for a set of twelve groups of commodities using the 2012/2013 Ghana Living Standards Survey. Unlike previous studies we use the GMM 3SLS estimator, which provides more efficient parameter estimates due to heteroskedastic errors inherent in cross-sectional datasets of this nature.

resultsThe results show that Ghanaian households that spend on tobacco are more likely to spend also on alcohol, recreation, transport and communications, but less on food, housing, and health needs.

conclusionsTobacco expenditure, through its 'crowding-in' effects on alcohol and 'crowding-out' effects on food and health expenditure worsens household welfare in Ghana.
