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

purposeTo date, molecular methods that circumvent the limitations of traditional culture methods have not been used to describe the vaginal microflora in India. Here, we compared culture and culture-independent molecular methods in characterizing the vaginal microbiota in Indian women. METHODOLOGY: Culture methods involved traditional cultivation on Rogosa and sheep blood agar, whereas culture-independent methods bypassed a culturing step by performing broadrange 16S rDNA PCR on DNA isolated directly from vaginal swabs.

resultsA total of 13 women were included in the study, of which five were characterized as healthy, two were bacterial vaginosis intermediate and six were bacterial vaginosis positive according to Nugent scoring. Lactobacillus jensenii was detected most frequently when using culture methods. On the other hand, Lactobacillus iners, which was not detected by culture methods, was the most common Lactobacillus sp. detected using cultivation-independent methods.

conclusionWe found little overlap between the species found using cultivation-dependent and cultivation-independent methods. Rather, culture-dependent and culture-independent methods were found to be complementary in describing the vaginal microflora among South Indian women. Culture-independent methods were found to be superior in detecting clinically relevant vaginal flora.
