Contrasting geographic distribution profiles of the herpes simplex virus type 1 BgOL and BgKL variants in Japan suggest dispersion and replacement.

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
Thelifelong latent infection-reactivation mode of infection of herpes simplex virus type 1 (HSV-1) transmitted by close contact has allowed a diversity of restriction fragment length polymorphism (RFLP) variations to accumulate in human populations. Whether and how the variants of the HSV-1 that is ubiquitous worldwide spread to different human populations is not clear. In our previous study the geographically gradient distribution of the HSV-1 BgK(L) variant, which is a good marker for the BgK(L):SaCFJ(M):SaGH(M):SaD/E(L):KpM(S) variant, suggested that BgK(L) dispersed geographically. Southern hybridization analyses showed that in BgK(L) the BglII cleavage site between the BglII K and small "Q/#13" fragments is lost, the SalI cleavage sites between the SalI J and C and between SalI F and J fragments are lost, and the SalI E fragment is abnormally large (SaE(L) variation). The RFLP and geographic distribution of one more HSV-1 RFLP variant, BgO(L), were comparatively analyzed. The BglII cleavage site between the BglII O and Q/#13 fragments is lost in BgOL. BgO(L) clinical isolates were not associated with any of the SaCFJ(M), SaE(L), SaGH(M), or KpM(S) variations, whereas one-fourth of the non-BgO(L):non-BgK(L) isolates was associated with SaCFJ(M) and SaGH(M), indicating that BgK(L) and BgO(L) are distant in terms of diversification. BgO(L) is distributed highly in the northeastern region and the southwestern island of Kyushu but is rare between the two regions in Japan, in a remarkable contrast to BgK(L). These are the first epidemiologic data to show contrasting geographic distribution profiles of two HSV-1 variants and suggest the gradual dispersion and replacement of HSV-1 variants.
