Near-infrared spectroscopy to monitor cerebral and renal oxygen saturation during cardiopulmonary bypass surgery for paediatric congenital heart disease: study protocol for a prospective observational cohort trial.
Article in BMJ open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled 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.
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
backgroundCurrent indicators for monitoring intraoperative organ function remain predominantly indirect, delayed and non-specific, particularly in paediatric populations undergoing congenital heart surgery, where multifactorial influences further complicate functional assessments. Emerging evidence suggests that the use of near-infrared spectroscopy (NIRS) technology to continuously monitor the regional oxygen saturation (rSO METHODS AND ANALYSIS: In this prospective observational cohort study, patients ≤18 years, scheduled for CHD surgery under cardiopulmonary bypass (CPB), will be enrolled after obtaining written informed consent. Exclusion criteria include pre-existing neuropsychiatric disorders, chronic kidney disease or other related disorders. Dual-channel NIRS probes will be applied to simultaneously monitor cerebral and renal rSO ETHICS AND DISSEMINATION: This study has been approved by the Institutional Review Board of Beijing Children's Hospital (approval number: [2024]-Y-093-D). Prior to enrolment, written informed consent will be obtained from the parents or legal guardians of all participating minors. The findings of this research will be disseminated through peer-reviewed publications and presentations at relevant conferences and shared with participating communities via lay summaries and social media platforms. TRIAL REGISTRATION NUMBER: The study was registered with the Chinese Clinical Trial Registry on 18 April 2024 (ChiCTR2400083225).
