Associations between generic substitution and patients' attitudes, beliefs and experiences.
Trial report in European journal of clinical pharmacology, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 18 papers, 3 of them syntheses that pooled 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.
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
backgroundGeneric substitution has been implemented in many countries, but knowledge about patients' attitudes, beliefs and experiences is still sparse.
aimTo assess associations between generic switching and patients' attitudes, beliefs and experiences with previous generic switching. DESIGN AND
settingA cross-sectional study comprising questionnaire responses from 2,476 randomly selected patients aged 20 years or older and living in the Region of Southern Denmark, who had redeemed substitutable drugs.
methodsThe questionnaire included items on beliefs about medicine, views on generic medicine and confidence in the healthcare system. Only prescriptions issued by the general practitioners were included. For each patient, we focused on one purchase of a generically substitutable drug (index drug). Patients were identified by means of a dispensing database.
resultsEarlier generic switches within the index ATC code were statistically significantly associated with experience of a generic switch (adjusted OR 5.93; 95 % CI 4.70-7.49). Having had more than five earlier switches within other ATC codes and having negative views on generic medicines reduced the odds of experiencing a generic switch. No associations were found between generic substitution and gender, drug group, number of different drugs used by the patient, confidence in the health care system and beliefs about medicine in general.
conclusionPatients who had once experienced a generic switch were more likely to accept a future generic switch within the same ATC code. Negative views on generic medicines were negatively associated with switching, while beliefs about medicine and confidence in the healthcare system had no influence.
