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.
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
introductionThis study examines the long-term effect of the COVID-19 pandemic on the reach and impact of one US state tobacco quitline while taking into account quitline offers of free nicotine replacement therapy (NRT).
methodsThis is a pre-post analysis from January 2017 through June 2023 of the reach and impact of Michigan's tobacco quitline after the start of the COVID-19 pandemic. We assess quitline reach (number of callers per month), effectiveness (self-reported 30-day abstinence at 6 months), and impact (number of new ex-tobacco users per month). We examine the main effects and interactions between pandemic status (i.e. pre vs post March 2020) and quitline offers of free NRT.
resultsThe COVID-19 pandemic had a persistent negative effect on quitline reach (p=0.002) and impact (p<0.001). Abstinence rates decreased transiently during the first year of the pandemic. Offering free NRT had a positive effect on quitline reach (p<0.001) and impact (p<0.001) before and after the start of the pandemic. For quitline reach, we found a significant interaction between pandemic and free NRT effects with a substantial decrease in the mean number of callers per month after the pandemic during months when free NRT is being offered (750; 95% CI: 545-1033, pre-pandemic vs 302; 95% CI: 233-392, post-pandemic) compared to months when free NRT is not being offered (247; 95% CI: 187-327, pre-pandemic vs 159; 95% CI: 114-221, post-pandemic).
conclusionsThere is a critical need to assess and address the ongoing effects of the COVID-19 pandemic on tobacco quitline reach and impact.
