The issue is whether claimant proved by a preponderance of the evidence that her need in 1982 for medical services for chronic low back strain was materially caused by her 1980 compensable injury. If so, SAIF must pay her medical expenses. ORS 656.245. The referee held that she did; the Workers’ Compensation Board reversed. On de novo review, ORS 656.298(6), we agree with the referee.

Reversed; referee’s order reinstated.
