Trial report in Health services research, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT00874510 (Interventions to Improve Fatigue Management Among Physician Trainees), which is not on this map. Cited by 32 papers, 1 of them a synthesis that pooled it.

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.

Abstract

objectiveTo compare the effects of lottery-based and fixed incentives on clinicians' response to surveys. DATA SOURCES: Three randomized trials with fixed payments and actuarially equivalent lotteries. STUDY

designTrial 1 compared a low-probability/high-payout lottery, a high-probability/low-payout lottery, and no incentive. Trial 2 compared a moderate-probability/moderate-payout lottery with an unconditional fixed payment (payment sent with questionnaire). Trial 3 compared a moderate-probability/moderate-payout lottery with a conditional fixed payment (payment promised following response). PRINCIPAL

findingsNeither the low-probability nor high-probability lotteries improved response compared with no incentive. Unconditional fixed payments produced significantly greater response than actuarially equivalent lotteries, but conditional fixed payments did not.

conclusionsLottery-based incentives do not improve clinicians' response rates compared with no incentives, and they are inferior to unconditional fixed payments.
