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

introductionClinical decision-making is a daily practice conducted by medical practitioners, yet the processes surrounding it are poorly understood. The influence of 'shortcuts' in clinical decision-making, known as heuristics, remains unknown. This paper explores heuristics and the valuable role they play in medical practice, as well as offering potential solutions to minimize the risk of incorrect decision-making.

methodThe quasi-systematic review was conducted according to modified PRISMA guidelines utilizing the electronic databases Medline, Embase and Cinahl. All English language papers including bias and the medical profession were included. Papers with evidence from other healthcare professions were included if medical practitioners were in the study sample. DISCUSSION: The most common decisional shortcuts used in medicine are the Availability, Anchoring and Confirmatory heuristics. The Representativeness, Overconfidence and Bandwagon effects are also prevalent in medical practice. Heuristics are mostly positive but can also result in negative consequences if not utilized appropriately. Factors such as personality and level of experience may influence a doctor's use of heuristics. Heuristics are influenced by the context and conditions in which they are performed. Mitigating strategies such as reflective practice and technology may reduce the likelihood of inappropriate use.

conclusionIt remains unknown if heuristics are primarily positive or negative for clinical decision-making. Future efforts should assess heuristics in real-time and controlled trials should be applied to assess the potential impact of mitigating factors in reducing the negative impact of heuristics and optimizing their efficiency for positive outcomes.
