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

The cost-effective and high-yield production of hyaluronic acid (HA) by microbial means remains challenging, necessitating the optimization of existing processes through the implementation of novel approaches. The present study investigates the production of HA under varying temperature and pH conditions utilizing independent, fully controlled fermenters. The synthesis of HA was evaluated at four temperatures (32 °C, 35 °C, 37 °C, 40 °C) and four pH levels (6.5, 7.0, 7.5, and 8.0), with optimal parameters identified through the Taguchi design methodology. The Taguchi optimization method effectively identified 37 °C and pH 6.5 as the optimal conditions for HA production corresponding to the highest signal-to-noise (S/N) ratios of 58.18 and 57.55, respectively. These conditions resulted in a maximum yield of 1.08 g.L
