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

Objective: Delay discounting refers to the devaluation of future rewards as a function of time. Previous studies proposed the relationship between time perception and delay discounting in ageing, while there is a lack of evidence about the effect of different dimensions of time. Method: This study explored the effect of delay length (1-day, 1-month, 6-month, 1-year, 5-year), time framing (delay, date) and time estimation (internal clock) on delay discounting in younger and older adults. Seventy younger adults and 57 older adults completed the delay discounting task and time estimation task. Results: Results suggested the effect of age, but there were no effects of delay lengths and time framing on age differences in delay discounting. Meanwhile, internal clock predicted delay discounting in older adults, with higher discounting correlating with more internal clock variability. Conclusion: Age differences in delay discounting may not be due to the effects of delay lengths and time framing, but rather to variations in the internal clock among older adults.
