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

objectiveTo investigate whether California's 2017 cigarette tax increase was passed onto smokers equally.

methodsAuditors recorded 4 cigarette prices in the same random sample of licensed tobacco retailers (N = 1049) before the tax increase (January-March 2017) and after (April-September 2018): Natural American Spirit (ultra-premium), Newport menthol (premium), and Pall Mall (value) all from the same manufacturer, and Marlboro (premium). Ordinary least squares regressions examined how the gap in prices (increase greater or less than $2.00 tax) varied by market segment and neighborhood demographics, controlling for store type and months since implementation. Paired t-tests assessed whether industry/retail revenue (price in excess of state and federal excise taxes) increased.

resultsOver-shifting (increase greater than tax) was evident for all 4 brands and was significantly greater for ultra-premium (Mean = $0.40, SD = 0.75) than premium (Mean = $0.25, SD = 0.78) and greater for premium than value brand (Mean = $0.16, SD = 0.67). However, under-shifting (increase less than tax) was evident for Newport in African-American neighborhoods and Pall Mall in Hispanic neighborhoods. After the tax increase, prices were significantly more likely to be discounted and significantly more stores advertised a discount on cigarettes.

conclusionCalifornia's tax increase was not passed onto consumers equally. Non-tax mechanisms to increase price could support intended effects of tobacco taxes.
