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

objectiveTo assess the nature and extent of physical-health comorbidities in people with schizophrenia and related psychoses compared with controls.

designCross-sectional study.

setting314 primary care practices in Scotland.

participants9677 people with a primary care record of schizophrenia or a related psychosis and 1 414 701 controls. Main outcome measures Primary care records of 32 common chronic physical-health conditions and combinations of one, two and three or more physical-health comorbidities adjusted for age, gender and deprivation status.

resultsCompared with controls, people with schizophrenia were significantly more likely to have one physical-health comorbidity (OR 1.21, 95% CI 1.16 to 1.27), two physical-health comorbidities (OR 1.37, 95% CI 1.29 to 1.44) and three or more physical-health comorbidities (OR 1.19, 95% CI 1.12 to 1.27). Rates were highest for viral hepatitis (OR 3.98, 95% CI 2.81 to 5.64), constipation (OR 3.24, 95% CI 3.00 to 4.49) and Parkinson's disease (OR 3.07, 95% CI 2.42 to 3.88) but people with schizophrenia had lower recorded rates of cardiovascular disease, including atrial fibrillation (OR 0.62, 95% CI 0.51 to 0.73), hypertension (OR 0.71, 95% CI 0.67 to 0.76), coronary heart disease (OR 0.75, 95% CI 0.61 to 0.71) and peripheral vascular disease (OR 0.83, 95% CI 0.71 to 0.97).

conclusionsPeople with schizophrenia have a wide range of comorbid and multiple physical-health conditions but are less likely than people without schizophrenia to have a primary care record of cardiovascular disease. This suggests a systematic under-recognition and undertreatment of cardiovascular disease in people with schizophrenia, which might contribute to substantial premature mortality observed within this patient group.
