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

backgroundThere is a need to investigate how adopting different strategies for treating obesity in different countries in the European Union affects the psychological well-being of patients.

aimsThe aim of this study was to perform a comparative evaluation of psychiatric symptoms (depression, anxiety and stress) in patients undergoing bariatric surgery versus patients receiving conservative treatment for morbid obesity in Poland and Germany.

methodA multicentre international prospective cohort study with 155 patients who underwent bariatric surgery and 409 patients who received conservative weight reduction treatment. Evaluation of the psychiatric symptoms was carried out for each patient at baseline and after 12 months of active treatment using a standardised Depression Anxiety Stress Scale questionnaire (DASS-21) questionnaire.

resultsAfter 12 months of active treatment, the level of psychiatric symptoms (depression, anxiety and stress) significantly decreased in both groups of patients: surgically treated versus conservatively treated patients from Poland and also from Germany. The median change in level of psychiatric symptoms among patients from both countries was significantly higher among surgically treated patients compared with conservatively treated patients (Poland P < 0.0001; Germany P < 0.0001). Improvements in the patient's mental health as a consequence of treatment were dependent on the specific strategy for treating obesity adopted in the analysed countries, the percentage of total weight loss and on gender.

conclusionsThe use of bariatric surgery in both Poland and Germany compared with non-surgical treatment for obesity resulted in more measurable benefits in the form of a decrease in psychiatric symptoms (depression, anxiety and stress) and reduction in body weight.
