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.

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.

Abstract

Incentives are used to improve many health-related behaviors, but evidence is mixed for their effectiveness both during the incentivization period and, even more so, on the persistence of the behavior after incentives are withdrawn. In this paper, we present the results of a randomized controlled trial that successfully uses incentives to improve medication adherence among HIV-infected patients in Uganda over 20 months, and follows the sample for another 6 months to measure the persistence of these behavioral improvements. Our study contributes to the literature on habit formation by identifying a behavioral strategy that is associated with persistently high medication adherence after controlling for observable individual-level characteristics and the receipt of incentives. We find evidence supporting a psychological theory of habits as reflexive context-behavior associations, which suggests new ways of designing incentive-based interventions for better promoting persistent, healthier behaviors.
