Evaluation of Paper-Based Point of Care Screening Test for Sickle Cell Disease.
Article in Indian journal of clinical biochemistry : IJCB, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
The aim of the study is to evaluate the stability and longevity of the paper-based screening test for the sickle cell disease in relation to different temperatures and storage time. Blood stain patterns were interpreted after spotting the blood-buffer mixture (phosphate buffer, saponin and sodium metabisulfite) on chromatographic paper (Whatman no. 3). The stability of the buffer was tested after keeping the buffer at different temperature for 24 h. Longevity of the buffer was tested post storage for various time intervals. Test indicated reproducibility with the buffer stored at 4°C. The 15% metabisulfite buffer was found to be stable up to 180 days at 4°C and showed accurate identification of all genotypes. The tests revealed 100% sensitivity and 100% specificity in identification of HbS. However, the sensitivity of differentiation between sickle cell trait (AS) with disease (SS) was found to be 97.7% with 100% specificity. The paper-based screening test may be used as a method of choice for the screening of sickle cell anemia in community-based screening programs. The low-cost, rapid, and accurate point of care testing tools offer an avenue for effective screening in developing nations.
