Predictive ability of serum osmolarity for contrast-induced nephropathy after elective percutaneous coronary intervention: Are we having a new target?
Article in The Egyptian heart journal : (EHJ) : official bulletin of the Egyptian Society of Cardiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundContrast-induced nephropathy (CIN) remains a serious complication following percutaneous coronary intervention (PCI), often leading to poor outcomes. Although the overall incidence of CIN is low, the risk can be significantly higher in certain susceptible cohorts.
resultsThis prospective observational analytic study enrolled 174 consecutive eligible patients. The study selectively included diabetic patients with heart failure who are receiving regular diuretic therapy, being scheduled for elective coronary angiography (CAG) and/or PCI. CIN occurred in 24.7% of the study participants. CIN patients had significantly higher baseline osmolarity compared to those who did not develop CIN. After adjusting for other factors, pre-procedure osmolarity ≥ 302.3 mOsm/L, higher CHA
conclusionsIn patients at high risk for CIN, serum osmolarity can serve as a practical stratification tool for CIN risk before elective CAG or PCI. Future studies should evaluate whether targeting a specific pre-procedural osmolarity threshold can reduce the risk of post-PCI CIN.
