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

backgroundIn November 2016, California voters approved Proposition 56, increasing the cigarette tax by $2.00 per pack and nearly tripling spending on tobacco prevention. This study examined whether the initiative was associated with increased smoking cessation.

methodsStates in the United States were categorized into 3 groups: California, 18 other states (including the District of Columbia) that raised taxes, and 32 states that did not raise taxes. Tax and price increases, tobacco prevention spending per capita, 3-month smoking cessation rates using data from the Behavioral Risk Factor Surveillance System (N = 443 054), and the proportion of daily smoking were compared for 2014-2016 and 2017-2019 for these groups.

resultsCalifornia had the largest increases in cigarette price (30.8%) and tobacco prevention spending (271.9%), both adjusted for inflation. Other states that raised taxes experienced price increases of 6.3% on average. The 3-month smoking cessation rate in California increased from 11.5% in 2014-2016 to 14.2% in 2017-2019 (P = .005). Among other states that raised taxes in that timeframe, cessation rates did not change significantly, from 8.6% to 8.7% (P = .755). Among states that did not raise taxes, cessation rates declined significantly, from 9.5% to 9.0% (P = .026). California also had a significant reduction in the proportion of daily smokers among those who did not quit (from 60.4% to 56.4%, P = .012).

conclusionsA major cigarette tax increase was associated with increased smoking cessation in California. Policies increasing tobacco taxes and re-investing new revenue in tobacco prevention can increase population cessation.
