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

purposeTo analyze the minimum inhibitory concentration (MIC) of isolates from fungal keratitis to natamycin and voriconazole and to assess the relationship between organism, MIC, and clinical outcome.

methodsData were collected as part of a randomized, controlled, double-masked clinical trial. Main outcome measures included best spectacle-corrected visual acuity, infiltrate/scar size, time to reepithelialization, and perforation. Speciation and analysis of MIC to natamycin and voriconazole were done according to Clinical and Laboratory Standards Institute standards. The relationship between MIC and organism, organism and outcome measure, and each outcome measure and MIC were assessed.

resultsOf the 120 samples obtained in the trial, 84 isolates had an identifiable organism and were available for further analyses. Fusarium spp and Aspergillus spp were the most commonly isolated organisms. MIC was significantly different across the groups of organisms (P = 0.0001). A higher MIC was significantly associated with an increased likelihood of perforation [odds ratio (OR), 2.03; 95% confidence interval (CI), 1.02-4.04; P = 0.04]. There was no significant association between MIC and 3-week visual acuity (OR, 0.058; 95% CI, -0.01 to 0.13; P = 0.11), 3-month visual acuity (OR, 0.01; 95% CI,-0.08 to 1.04; P = 0.79), 3-week infiltrate/scar size (OR, 0.12, 95% CI, -0.02 to 0.27; P = 0.10), 3-month infiltrate/scar size (OR, 0.12; 95% CI, -0.02 to 0.25; P = 0.09), or time to reepithelialization (hazards ratio, 1.19; 95% CI, 0.98-1.45; P = 0.08).

conclusionA higher MIC was associated with an increased odds of perforation. The results of this study suggest that resistance to antifungal medication may be associated with worse outcomes in fungal keratitis.
