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

backgroundHuman blood groups are polymorphic and inherited integral structures of the red cell membrane. More than 300 red cell antigens have been identified and further categorized into 30 major discrete systems. Their distribution varies in different communities and ethnic groups.

aimsThis work was set to determine the prevalence of red cell phenotypes in donors from the major ethnic groups in Malaysia, namely, Malays, Chinese, and Indians. MATERIALS AND

methodsThe work utilized the dextran acrylamide gel technique in which four types of gel cards were used to identify the blood groups of 594 subjects collected at the National Blood Transfusion Centre, Malaysia.

resultsBlood group O and CDe/CDe (R1R1) were the most common in all ethnic groups. The cde/cde (rr) was more prevalent amongst Indians. The rare phenotypes found were cDE/cDE(R2R2) and cDE/CDE(R2Rz). With the Lewis system, the distribution of Le(a-b+) was similar among the ethnic groups. The rarest phenotype Fy(a-b-) was discovered in two donors. Jk(a-b-) was found in seven Malays and in two Indians. In the MNSs system, MN was common in Malays and Chinese, while the MM was more common among Indians. The rare SS was found in 19 donors. Malay and Chinese subjects had high P1 Negative blood but Indians showed high P1 positive blood. Within the Kell System, the very rare KK type was found in six subjects.

conclusionsThe results obtained serve as an established database for the distribution of red cell phenotypes based on the blood group systems of donors from the major ethnic groups in Malaysia.
