C-Reactive Protein Biosensor for Diagnosing Infections Caused by Orthopedic Trauma.

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
introductionInfections linked to orthopedic trauma are common complications that place a significant strain on the healthcare system. Immediate identification of the infection and its severity is essential for providing effective treatment.
methodsC-reactive Protein (CRP) is a commonly used inflammatory marker in orthopedic surgery and has proven to be a valuable biomarker for diagnosing and monitoring infections. Specifically, CRP aids in the early identification of postoperative infections. This research work has focused on developing a highly sensitive CRP biosensor using iron oxide nanomaterial-modified dielectric sensors.
resultsGold Urchin (GU)-conjugated aptamers and antibodies were used as probes and attached to the electrode via amine linkers. The aptamer-GU-antibody-modified electrode detected CRP at concentrations as low as 1 pg/mL, with an R2 value of 0.9942. Furthermore, CRP-spiked serum exhibited an increase in current response at all concentrations of CRP, indicating selective detection of CRP. Additionally, control experiments using complementary sequences of the aptamer, relevant proteins, and non-immune antibodies did not enhance the current responses, confirming the specific identification of CRP.
conclusionThe sensing strategy has enabled the detection of CRP at its lowest levels, facilitating the identification of infections during orthopedic surgery and subsequent treatment.
