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 low survival rate of high-quality baijiu yeast, Modified Sporidiobolus Johnsonii A (MSJA), during spray drying and the unclear mechanisms underlying its stress treatment processes (heat shock, acid shock, and salt stress) have significantly hindered its low cost and high effective application, thereby impacting the high-quality development of the liquor industry. To address this problem. A response surface experiment was first conducted to optimize the stress treatment process prior to spray drying. Subsequently, the mechanisms and efficacy of the stress treatments were analyzed using Field Emission Scanning Electron Microscopy (FESEM). The results demonstrated that the survival rate of spray-dried MSJA could be improved from 38.5 to 54.8% under the optimal conditions, with heat shock temperature (X) = 35.2 °C, acid stress pH (Y) = 3.2, and salt stress concentration (Z) = 4 g/L KH
