Efficacy of varenicline versus bupropion for smoking cessation: A systematic review and meta-analysis of randomized controlled trials.
Review in Indian journal of psychiatry, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
According to the Global Burden of Disease (GBD) Study conducted in 2019, smoking tobacco leads to over 8 million deaths each year. Hence, it is crucial to identify optimal smoking cessation therapy. To compare the efficacy of varenicline versus bupropion for smoking cessation by performing a meta-analysis of randomized controlled trials (RCTs). Protocol was registered in the International Prospective Register of Systematic Reviews (PROSPERO). The Patient intervention comparison outcome time (PICOT) format is used in the study. Patients having nicotine use disorder treated with varenicline or bupropion were included, and the continuous abstinence rate (CAR) was assessed at 12, 24, and 52 weeks. The PubMed and Google Scholar databases were systematically searched, and after the screening, RCTs involving a comparison of varenicline and bupropion in smoking cessation were included. We performed a meta-analysis of three RCTs (10110 patients) by RevMan 5.4.1 statistical software to determine the efficacy of varenicline compared with bupropion in smoking cessation. The CAR at 9- to 12-week follow-up of varenicline is superior to bupropion (OR = 1.79, CI range: 1.59-2.02,
