Assessment of the Radio-contrast Media-Induced Self-Reported Adverse Drug Reactions in a Tertiary Care Hospital of North India: A Prospective Study.
Article in International journal of applied & basic medical research. 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
Background: Radio-contrast media are the agents which are used on daily basis in the radiological practice for either diagnostic or therapeutic purpose. Currently used agents are considered to be safe but not devoid of side effects. Objectives: Objectives of the study were to assess the incidence of adverse drug reactions (ADRs) in the patients who receive radiographic contrast media for computed tomography (CT) and intravenous pyelography (IVP), to stratify the ADRs into different types based on their time of appearance and as per their severity. Materials and Methods: A prospective and observational study of 1-year duration was done on all the patients who received radio-contrast media (Iohexol) intravenously for CT and IVP in the radiodiagnosis department. Patients who experienced ADRs were recorded for the basic demographic characteristics and types of ADRs. Stratification of ADRs as per their severity was done using common terminology criteria for adverse events scale and Modified Hartwig and Siegel ADR Severity Assessment Scale, and casualty assessment was done using Naranjo's Algorithm. Results: Out of the total 3522 patients who were included in the study, eight patients got 12 suspected ADRs with some of the patients having more than one type of ADR. The most frequent ADR was nausea and vomiting (25%), followed by fever, chills, or sweating. Incidence of ADRs was 0.23%. All the ADRs were acute and occurred within 30 min of contrast administration. As per the severity scales used, all the ADRs were mild (75%) to moderate (25%) in nature with none of the reactions to be severe. Causality assessment showed 87.5% of the reactions to be "probable" in nature. Conclusion: Low osmolar nonionic radio contrast media are associated with very low incidence of ADRs in the North Indian population.
