Psychologically Informed Implementations of Sugary-Drink Portion Limits.
Article in Psychological science, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 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
In 2012, the New York City Board of Health prohibited restaurants from selling sugary drinks in containers that would hold more than 16 oz. Although a state court ruled that the Board of Health did not have the authority to implement such a policy, it remains a legally viable option for governments and a voluntary option for restaurants. However, there is very limited empirical data on how such a policy might affect the purchasing and consumption of sugary drinks. We report four well-powered, incentive-compatible experiments in which we evaluated two possible ways that restaurants might comply with such a policy: bundling (i.e., dividing the contents of oversized cups into two regulation-size cups) and providing free refills (i.e., offering a regulation-size cup with unlimited refills). Bundling caused people to buy less soda. Free refills increased consumption, especially when a waiter served the refills. This perverse effect was reduced in self-service contexts that required walking just a few steps to get a refill.
