Growth of M. avium subspecies paratuberculosis in culture is enhanced by nicotinic acid, nicotinamide, and α and β nicotinamide adenine dinucleotide.

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
backgroundWithout known mechanisms of action, Crohn's disease is exacerbated, and ulcerative colitis is improved, by the use of tobacco. Mycobacterium avium subspecies paratuberculosis (MAP) may be zoonotic. We hypothesized that tobacco components might alter the growth kinetics of MAP, explaining these divergent clinical observations.
methodsThe effect of nicotine, nicotinic acid, nicotinamide and α and β nicotinamide adenine dinucleotide (α and β NAD) were studied on eight strains of three mycobacterial species (MAP, M. avium and M. tb. complex). Data are obtained as "cumulative growth index," (cGI) and presented as "percent increase in cumulative GI" (% + ΔcGI).
resultsNicotinic acid enhances the two human MAP isolates (Dominic; 225% + ΔcGI and UCF-4; 92% + ΔcGI) and M. avium (ATCC 25291; 175% + ΔcGI). Nicotinamide (at 6.4 µg/ml) enhances the human MAP isolates (Dominic; 156% + ΔcGI and UCF-4; 79% + ΔcGI) and M. avium (ATCC 25291; 144% + ΔcGI.) Both α and β NAD enhance Dominic; (135 and 150 % + ΔcGI) and UCF-4; (81 and 79% + ΔcGI). At the doses tested, nicotine has no effect on any strain studied.
conclusionsWe show enhancement of MAP growth by nicotinic acid, one of ≥4,000 tobacco-related molecules, its amide, nicotinamide and α and β NAD. Pure nicotine has no enhancing effect at the doses studies.
