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.

2 · The registry

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: Diabetes mellitus (DM) is a major global issue, with a prevalence of 11.1%. In Africa, South Africa is recognized as having one of the highest prevalences. Limited access to timely glycated haemoglobin (HbA1c) testing may delay treatment adjustments for diabetic patients. Point-of-care (POC) analysers provide faster results, potentially enhancing diabetes management. This study aimed to evaluate the performance of a POC device compared to a laboratory-based method, including the effect of potentially interfering haemoglobin (Hb) variants. Methods: HbA1c was measured in whole blood and capillary samples from 63 diabetic patients using the Finecare™ HbA1c POC device and compared to the Bio-Rad Variant II, a laboratory method utilising ion-exchange high-performance liquid chromatography (HPLC). 43 whole blood samples identified with Hb variants from routine laboratory HPLC analysis were also assessed on the POC device. Results: The POC device demonstrated a strong correlation with HPLC for both capillary (r = 0.94, 95% CI 0.90-0.96) and whole blood samples (r = 0.94, 95% CI 0.91-0.97). Mean bias was 1.3% (95% CI -1.2-3.8) for capillary vs. HPLC, and 4.5% (95% CI 2.1-6.9) for whole blood vs. HPLC. However, POC HbA1c in samples with Hb variants showed poor correlation with HPLC (r = 0.60, 95%CI 0.37-0.77) and a mean bias of -2.8% (95%CI -7.2-1.5). Conclusion: The Finecare™ HbA1c POC device performed acceptably for both capillary and whole blood samples, comparable to the HPLC method. We recommend capillary samples for routine monitoring but advise caution in populations with a high prevalence of Hb variants.
