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.

2 · The registry

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

We test the value of unconditional non-monetary gifts as a way to improve health worker performance in a low income country health setting. We randomly assigned health workers to different gift treatments within a program that visited health workers, measured performance and encouraged them to provide high quality care for their patients. We show that unconditional non-monetary gifts improve performance by 20 percent over a six-week period, compared to the control group. We compare the impact of the unconditional gift to one in which a gift is offered conditional on meeting a performance target and show that only the unconditional gift results in a statistically significant improvement. This demonstrates that organizations can improve the performance of health workers in the medium term without using financial incentives.
