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
Opioid-induced constipation (OIC) is one of the major side effects in patients receiving methadone maintenance treatment (MMT). Quite often, constipation becomes a factor significantly affecting therapeutic options and choices. Currently used approaches are symptomatic and in many cases ineffective. At the same time, it is well known that the gastrointestinal system is a subject for psychosomatic influences. In this case report, we describe an unexpected outcome of placebo administration in a patient suffering from OIC since her participation in MMT. The patient participated in a triple-blind randomised placebo-controlled trial of naloxone for treatment of OIC. As part of the study crossover design, the patient received 1 week of placebo followed by 1 week of naloxone, and had significant improvement in her bowel functioning when receiving placebo, then returned to baseline during the second week of the study.
