Impact of near-infrared vein imaging on peripheral intravenous access success rates in geriatric patients: a systematic review and meta-analysis.
Synthesis in BMC geriatrics, 2026. 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
objectiveTo evaluate the efficacy of near-infrared (NIR) light devices in improving peripheral intravenous cannulation (PIVC) success rates among older patients.
methodsA systematic literature search of PubMed, EMbase, The Cochrane Library, and several Chinese databases (Wanfang Data, CNKI, CBM, VIP) was conducted from inception to July 16, 2025, for randomized controlled trials (RCTs) and observational studies involving patients aged ≥ 65 years. Two investigators independently screened studies, extracted data, and assessed methodological quality using predefined criteria. Meta-analyses were performed via RevMan 5.3 software.
resultsEight studies were included (n = 1,022 participants). The meta-analysis demonstrated significantly higher first-attempt success rates in the NIR group compared to the standard care group (OR = 2.36, 95% CI: 1.73–3.21, P < 0.001,I2 = 59.0%). NIR technology also reduced procedure time (SMD = − 1.45, 95% CI: −1.64 to − 1.26, P < 0.001,I2 = 0%), lowered complication rates (OR = 0.37, 95% CI: 0.23–0.59, P < 0.001,I2 = 19%), improved patient satisfaction (OR = 1.90, 95% CI: 1.33–2.72, P = 0.0004,I2 = 30%), and reduced anxiety levels (SMD = − 1.70, 95% CI: −2.80 to − 0.59, P < 0.001,I2 = 96%).
conclusionCompared to conventional methods, NIR-based vascular visualization technology may enhance first-attempt PIVC success rates in older patients while reducing procedure time, complication risks, and anxiety. However, the certainty of evidence is limited by study heterogeneity and risk of bias. These findings highlight its potential clinical utility for optimizing vascular access in geriatric care, particularly for patients with anticipated difficult venous access.
