HIV-1 maternal and infant variants show similar sensitivity to broadly neutralizing antibodies, but sensitivity varies by subtype.
Article in AIDS (London, England), 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 13 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
rationaleTo protect against HIV infection, passively transferred and/or vaccine-elicited neutralizing antibodies (NAbs) need to effectively target diverse subtypes that are transmitted globally. These variants are a limited subset of those present during chronic infection and display some unique features. In the case of mother-to-child transmission (MTCT), transmitted variants tend to be resistant to neutralization by maternal autologous NAbs.
methodTo investigate whether variants transmitted during MTCT are generally resistant to HIV-1-specific NAbs, 107 maternal or infant variants representing the dominant HIV-1 subtypes were tested against six recently identified HIV-1-specific broadly neutralizing monoclonal antibodies (bNAbs), NIH45-46W, VRC01, PGT128, PGT121, PG9 and PGT145.
resultsInfant and maternal variants did not differ in their neutralization sensitivity to individual bNAbs, nor did viruses from transmitting versus nontransmitting mothers, although there was a trend for viruses from transmitting mothers to be less sensitive overall. No single bNAb neutralized all viruses, but a combination of bNAbs that target distinct epitopes covered 100% of the variants tested. Compared with heterosexually transmitted variants, vertically transmitted variants were significantly more sensitive to neutralization by PGT128 and PGT121 (P=0.03 in both cases), but there were no differences for the other bNAbs. Overall, subtype A variants were significantly more sensitive to NIH45-46 (P=0.04), VRC01 (P=0.002) and PGT145 (P=0.03) compared with the nonsubtype A and less sensitive to PGT121 than subtype Cs (P=0.0001).
conclusionA combination of bNAbs against distinct epitopes may be needed to provide maximum coverage against viruses in different modes of transmission and diverse subtypes.
