SS-31 (Elamipretide) by laboratory

The same compound measured by different laboratories on different gradients. Where the medians differ, the question is whether the material differed or the method did — and for SS-31 (Elamipretide), with a class minimum gradient of 15 min, the method is a live explanation.

Figure. SS-31 (Elamipretide) purity by contributing laboratory. Any offset between rows has two possible sources — a real difference in the material each laboratory happened to receive, and the laboratory's own bias — and this figure cannot separate them. The paired analysis that can is on inter-lab agreement.
