1 · What the graph read from 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.

Abstract

objectiveInfants are at a high risk of developing anaemia, which can arise from various causes, including inappropriate feeding practices. However, few infants attend anaemia screening programmes due to poor cooperation and being time-consuming. This study evaluated the accuracy of noninvasive total haemoglobin (Hb) spot-check monitoring as part of anaemia screening in healthy infants, compared with the conventional laboratory method.

designA cross-sectional study was conducted using a consecutive sampling technique.

settingThe study was carried out at the Well-Child Clinic, Khon Kaen University, Thailand.

participantsHealthy, full-term infants aged 6-12 months who were scheduled for vaccination. Spectrophotometric haemoglobin (SpHb) was measured using Masimo Rad-67 with Rainbow DCI-mini Sensor. These values were compared with conventional laboratory analysis (HbLab) performed on the same day. PRIMARY AND SECONDARY OUTCOME: Differences between Hb values using the two methods were analysed using the Bland-Altman method. Sensitivity, specificity and positive and negative predictive values (PPV and NPV) for detecting anaemia were determined. Anaemia was defined as HbLab of <11.0 g/dL.

resultsA total of 104 infants, with a median age of 9.6 (IQR 9.3, 10.9) months, were included. The prevalence of anaemia, defined by HbLab, was 38.46%. The mean SpHb was 12.20±1.10 g/dL, while the mean HbLab was 11.19±1.21 g/dL. A moderate positive correlation was observed (

conclusionA noninvasive tool for measuring Hb, with moderate sensitivity and NPV, may provide utility for initial screening to reduce unnecessary venipuncture in infants. However, its limited specificity and PPV necessitate confirmatory testing through conventional laboratory methods for accurate diagnosis. Depending on the context and available resources, it has potential to complement existing diagnostic processes, particularly in settings where rapid and noninvasive screening is prioritised. TRIAL REGISTRATION NUMBER: Thai Clinical Trials Registry (TCTR20210816002).
