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

backgroundClinical cancer trials are crucial for the implementation of new treatments in the clinical setting, but it is equally crucial that patients are given the opportunity to make a well-informed decision about participation. The inclusion process is complex, including both oral and written information about the trial. The process of patients' decision-making regarding clinical cancer trials has not yet been sufficiently studied. This interview study aims to explore the process of patients' reasoning regarding the decision to participate in a clinical cancer trial.

methodsThe study is based on 27 individual face-to-face interviews with patients who had decided to participate in a clinical cancer trial. The interviews were audio-recorded and transcribed verbatim and then analysed using inductive content analysis.

resultsContent analysis revealed 17 subthemes grouped into five themes: (1) an unhesitating decision to participate; (2) a decision based on flimsy grounds and guided by emotion; (3) feeling safe and secure with my decision; (4) faced with a choice versus what choice do I have? and (5) hoping for help while helping others. The decision to participate in a clinical cancer trial was often immediate and guided by emotions, based on a trusting relationship with healthcare personnel rather than on careful reading of written information. Palliative patients, in particular, sometimes had unrealistic beliefs about the effectiveness of the trial treatment.

conclusionsIt is vital that the decision to participate in a clinical cancer trial is preceded by an honest dialogue about possible positive and negative effects of the trial treatments, including other options such as supportive care in the palliative setting. Our findings also raise the questions of how important written information is for the decision-making process and also whether genuine informed consent is possible. To reach a higher degree of informed consent, it is most important that the oral information is given in a thorough and unbiased manner.
