The differential effects of FTY720 on functional recovery and infarct size following myocardial ischaemia/reperfusion.
Article in Cardiovascular journal of Africa. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
aimThe aim of this study was to evaluate the effects of the sphingosine analogue, FTY720 (Fingolimod), on the outcomes of myocardial ischaemia/reperfusion (I/R) injury.
methodsTwo concentrations of FTY720 (1 or 2.5 µM were administered either prior to (PreFTY), or following (PostFTY) 20 minutes' global (GI) or 35 minutes' regional ischaemia (RI) in the isolated, perfused, working rat heart. Functional recovery during reperfusion was assessed following both models of ischaemia, while infarct size (IFS) was determined following RI.
resultsFTY720 at 1 µM exerted no effect on functional recovery, while 2.5 µM significantly impaired aortic output (AO) recovery when administered prior to GI (% recovery: control: 33.88 ± 6.12% vs PreFTY: 0%, n = 6-10; p < 0.001), as well as before and after RI ( % recovery: control: 27.86 ± 13.22% vs PreFTY: 0.62% ; p < 0.05; and PostFTY: 2.08%; p = 0.0585, n = 6). FTY720 at 1 µM administered during reperfusion reduced IFS (% of area at risk (AAR): control: 39.89 ± 3.93% vs PostFTY: 26.56 ± 4.32%, n = 6-8; p < 0.05), while 2.5 µM FTY720 reduced IFS irrespective of the time of administration ( % of AAR: control: 39.89 ± 3.93% vs PreFTY: 29.97 ± 1.03% ; and PostFTY: 30.45 ± 2.16%, n = 6; p < 0.05).
conclusionFTY720 exerted divergent outcomes on function and tissue survival depending on the concentration administered, as well as the timing of administration.
