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

AIMS AND

methodPatients prescribed clozapine are increasingly living into old age. However, there is a lack of studies to guide prescribing in this age group. We sought to identify all clozapine patients in Hertfordshire Partnership NHS Foundation Trust over a 5-year period and review side-effect burden and co-prescribing in all patients aged over 65 years.

resultsWe identified 69 patients. The majority (61%) were stable in terms of mental state; 94% of cases had experienced a side-effect within the past year, with constipation occurring most commonly (65% of cases). CLINICAL IMPLICATIONS: Our findings reveal a significant side-effect burden, particularly in relation to constipation. Clozapine-induced gastrointestinal hypomotility (CIGH) can be fatal; however, increasing age has not been a recognised risk factor for constipation in clozapine patients to date. This raises questions about increasing risk to physical health as patients age and adds to concerns about the lack of monitoring for CIGH.
