The efficacy of varenicline in achieving abstinence among waterpipe tobacco smokers - study protocol for a randomized controlled trial.
Trial report in Trials, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled 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.
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
backgroundWaterpipe tobacco smoking has increased among youth across the globe including in the US, and it continues as a common and traditional form of smoking tobacco in Pakistan. A range of behavioral and pharmacological therapies are available to support people in quitting cigarette smoking; however, little evidence exists for the efficacy of these therapies in achieving abstinence among waterpipe tobacco smokers. The objective of this study is to assess the efficacy of varenicline when added to behavioral support for waterpipe tobacco smoking cessation, by measuring biochemically validated continuous abstinence in waterpipe tobacco smokers. METHODS/
designThis is a two-arm, double-blind, placebo-controlled randomized trial conducted in four districts in Punjab, Pakistan. Study participants include adults using a waterpipe (with or without concomitant cigarette, bidi or other forms of tobacco smoking) on a daily basis for at least 6 months and who are willing to quit. We will individually randomize 510 participants to one of the two arms of the trial. Participants in the intervention arm will receive varenicline and behavioral support and those in the control arm will receive placebo and behavioral support. The primary outcome will be continuous abstinence for at least 6 months (week 25) which is biochemically verified by a carbon monoxide level of <10 ppm. Secondary outcomes will include biochemically verified 7-day point abstinence at 5, 12 and 25 weeks and any lapses and relapses between the different assessment points. Tertiary outcomes will include assessment of withdrawal symptoms using the Mood and Physical Symptoms Scale (MPSS), smoking dependency using the Lebanon Waterpipe Dependency Scale (LWDS-11) and monitoring adverse outcomes. DISCUSSION: This is an efficacy trial and would require a subsequent effectiveness trial for a definitive evaluation of the intervention.
