Mortality risk and causes of death in exogenous Cushing's syndrome: a systematic review and meta-analysis.

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
contextChronic oral glucocorticoids (GCs) are widely prescribed for multiple diseases. Although long-term GC exposure causes systemic toxicity, the magnitude, dose-response relationship, and causes of GC-associated mortality remain incompletely defined.
objectiveTo quantify overall and cause-specific mortality associated with chronic oral GC exposure and evaluate dose-response relationships across underlying disease groups.
methodsWe conducted a systematic review and meta-analysis following PRISMA guidelines (PROSPERO CRD42017067530). PubMed/MEDLINE, EMBASE, Cochrane Library, Web of Science, and CINAHL were searched from 1945 to March 2019. Eligible studies reported standardized mortality ratios (SMRs) or absolute deaths among adults receiving chronic oral GCs. Random-effects meta-analysis and mixed-effects meta-regression were used to synthesize mortality and dose-response associations across GC exposure metrics, exposure duration, and disease subgroups.
resultsOne-hundred and sixteen studies encompassing 128 cohorts and 51 380 patients were included. Chronic GC exposure was associated with excess mortality (pooled SMR 1.87; 95%CI 1.32-2.61; I2 74.0%). The pooled proportion of death was 12.0% (95%CI 10-14%). Mortality risk was highest in inflammatory diseases (30.0%) and the vasculitides (18.0%). Higher cumulative dose (≥5 g prednisolone-equivalent), average daily dose >5 mg/day, and higher initial dose were each independently associated with increased mortality. Cardiovascular disease was the leading causes of death (25.6%), followed by malignancy (15.7%) and infection (13.4%).
conclusionChronic oral GC exposure was associated with increased mortality across disease groups, with higher cumulative and early-treatment doses correlating with higher risk. However, causal attribution remains uncertain due to confounding by indication, limited disease-severity data, and exposure misclassification. These findings support GC stewardship and targeted cardiovascular and infection risk mitigation, rather than indiscriminate dose reduction.
