Article in Mycopathologia, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04821193 (Comparison of the Effects of 5% NaHCO3, 2% Chlorhexidine Gluconate and 70% Alcohol for Prevention of Infections Related to Catheter Applications in Children.), which is not on this map.

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.

Abstract

Although sodium bicarbonate-NaHCO(3) (SB) has many domestic and medical, traditional and empirical uses, only little scientific documentation of its activity is available. The aims of this study were to investigate the antifungal activity of SB on the three fungal groups (yeasts, dermatophytes and molds) responsible for human skin and nail infections. We first evaluated the in vitro antifungal activity of SB on 70 fungal strains isolated from skin and nail infections: 40 dermatophytes, 18 yeasts and 12 molds. A concentration of 10 g/L SB inhibited the growth of 80% of all the fungal isolates tested on Sabouraud dextrose agar. The minimal inhibitory concentration 90 (MIC90) of SB measured on Sabouraud dextrose agar, Sabouraud dextrose broth and potato dextrose broth was 5 g/L for the yeasts, 20 g/L for the dermatophytes and 40 g/L for the molds. In a second step, we prospectively evaluated the ex vivo antifungal activity of SB on 24 infected (15 dermatophytes, 7 yeasts and 2 molds) clinical specimens (15 nails and 9 skin scrapings). The fungal growth was completely inhibited for 19 (79%) specimens and reduced for 4 (17%) specimens after 7 days of incubation on Sabouraud dextrose-chloramphenicol agar supplemented with 10 g/L of SB as compared to Sabouraud dextrose-chloramphenicol agar without SB. In conclusion, we documented the antifungal activity of SB on the most common agents of cutaneous fungal infection and onychomycosis, and we specified the effective concentrations for the different groups of pathogenic fungi. The mechanism of action of SB has yet to be explored.
