Triptan partition in model membranes.
Article in Journal of molecular modeling, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
In this work, we report a molecular dynamics simulations study of protonated triptans, sumatriptan and naratriptan, in a fully hydrated bilayer of 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphatidyl-choline (POPC). The simulations were carried out at two concentrations for each drug. Our results show partition between the lipid head-water interphase and water phase for both triptans, with increasing access to the water phase with increasing concentrations. The triptans were stabilized at the interphase through different specific interactions with the POPC bilayer such as hydrogen bonds, salt bridges, and cation-π. Besides, sumatriptan and naratriptan protonated molecules have no access to the hydrophobic region of the bilayer at the studied conditions. Similar results were found for both drugs, however protonated naratriptan shows slightly higher affinity for the water phase. This behavior was attributed to the bulky lateral amino group in its structure under the studied conditions (drugs were originally placed at the water phase). This work represents a first insight to the comprehensive understanding of triptan partition in model membranes.
