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

objectiveTo compare the efficacy and safety of recombinant anti-D (R-anti-D) with conventional polyclonal anti-D (Poly anti-D) in preventing maternal-fetal rhesus D (RhD) alloimmunization and to investigate the immunogenicity of R-anti-D.

methodsThis was a randomized, open-label, multi-center clinical trial conducted in RhD-negative pregnant women who did not receive antenatal anti-D who delivered RhD-positive babies and showed negative indirect Coombs tests (ICTs) at baseline. The women were randomized in a 2:1 ratio to R-anti-D or Poly anti-D groups and were administered 300 mcg (IM) of the corresponding drug within 72 hours of delivery. ICT was performed 72 hours, 90 days, and 180 days after anti-D injection. Serum samples were collected to check for the development of antibodies against R-anti-D at days 90 and 180, using bridging enzyme-linked immunosorbent assay. The proportion of subjects who had positive ICT results at days 90 and 180 were compared between the groups using Fisher's exact test.

resultsA total of 144 women were randomized to the R-anti-D group and 71 to the Poly anti-D group. Three women in the R-anti-D and none in the Poly anti-D group had a positive ICT result at day 90. No woman in either group had positive ICT result at day 180. Both drugs were well tolerated with only 4 reports of adverse events in each group-all were mild, non-serious, and resolved without sequelae. No subject developed antibodies against R-anti-D.

conclusionThe studied R-anti-D is comparable in efficacy to conventional Poly anti-D and is safe and non-immunogenic.
