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

Aim: Constipation in schizophrenia patients receiving antipsychotics can lead to severe intestinal complications, such as paralytic ileus or megacolon. Despite the clinical importance of the topic, few studies have thoroughly investigated the risk factors of constipation-related complications. Therefore, the present study aimed to identify clinical and pharmacological factors associated with severe, constipation-related conditions in patients with schizophrenia. Methods: The present, retrospective study analyzed inpatients with schizophrenia and constipation at Tokyo Metropolitan Matsuzawa Hospital between 2014 and 2018. Logistic regression analysis was performed to test for any association between severe, constipation-related conditions and patient demographics and the use of various antipsychotics, antiparkinsonian drugs, and anthraquinone stimulant laxatives. Results: Of the 4114 patients included, 556 had a severe, constipation-related condition. High dosages of clozapine (odds ratio [OR]: 8.688; 95% confidence interval [CI]: 1.926-39.186; Conclusion: These findings highlighted the need for careful monitoring of constipation and for optimizing antipsychotic drug regimens. The use of antiparkinsonian drugs and anthraquinone stimulant laxatives should be limited to the short term.
