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

A Lactobacillus-rich vaginal microbiome is associated with a reduced risk for sexually transmitted diseases and adverse reproductive health outcomes, with Lactobacillus crispatus identified as particularly beneficial. This study investigated the nutritional requirements of two vaginal isolates, L. crispatus RL09 and RL10, and presents a chemically defined medium (CDM) that supports their growth. This study experimentally validated that L. crispatus relies on exogenous fatty acids, essential B vitamins, including riboflavin (B2), niacin (B3) and pantothenate (B5), and all eighteen amino acids for sustained growth. On one hand, this body of work adds to the physiological understanding of Lactobacilliaceae and lays the groundwork for future quantitative studies on L. crispatus. On the other hand, we have shown that L. crispatus exhibits a high metabolic dependency on its environment. These dependencies underscore the potential sensitivity of L. crispatus to nutrient variations, which may influence its ability to dominate and maintain a healthy vaginal ecosystem.
