An assessment of the central disposition of intranasally administered insulin lispro in the cerebrospinal fluid of healthy volunteers and beagle dogs.
Trial report in Drug delivery and translational research, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled 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.
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
Intranasally administered regular insulin and insulin aspart have shown cognitive benefit for patients with Alzheimer's disease (AD). To support development of intranasally administered insulin analogs for AD, the central disposition of intranasal insulin lispro in the cerebrospinal fluid (CSF) of healthy volunteers was investigated. Healthy volunteers (N = 8) received two sequential doses of intranasal insulin lispro (48 or 80 IU followed by 160 IU) by Aero Pump in an open-label, single-period study with serial CSF and serum sampling over 5 hours after each dose. CSF insulin lispro was also measured in beagle dogs (N = 6/dose group) that received either 24 IU/kg (equivalent local nasal (IU/cm
