Role of nalidixic acid in isolation of Salmonella typhimurium strains capable of growth at 48 degrees C.

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
Salmonella typhimurium thermotolerant mutants dependent on the presence of nalidixic acid for growth at 48 degrees C were isolated and designated nalidixic acid-dependent, thermotolerant mutants, naldttl. Genetic mapping revealed that naldttl alleles map within the gyrA gene. When S. typhimurium strain Q was plated in the dark on nutrient agar containing nalidixic acid (20 micrograms/ml) as a photosensitizer and briefly exposed to white light or near VU light prior to incubation at 42 degrees C, nalidixic acid-resistant mutants arose in about 16 h at frequencies of 5 x 10(-8) for white light and 1 x 10(-6) for near UV light. About 10% of these nalidixic acid-resistant mutants derived from photodynamic mutagenesis exhibited the thermotolerant characteristic.
