PAIN AND PHYSICAL PERFORMANCE AMONG RECREATIONAL RUNNERS WHO RECEIVE A CORRECTION FOR AN ILIAC CREST HEIGHT DIFFERENCE: A CASE SERIES.
Article in International journal of sports physical therapy, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundLeg-length inequality (LLI) is a musculoskeletal condition where one lower extremity is longer than the other. There is conflicting evidence on the relevance of LLI and conservative treatment options. Iliac crest height difference (ICHD) is a good estimate of LLI.
objectiveTo observe changes in pain and performance among recreational runners with running-induced lower extremity pain who received ICHD correction.
methodsA 12-week case series with multiple baseline and intervention (A-B-A-B) phases was used to observe the effects of ICHD correction on pain and performance among three symptomatic recreational runners. Primary outcome measures included the Lower Extremity Functional Scale (LEFS), the Visual Analog Scale -Worst Pain (VAS-W), symptom-free running distance, and average running speed. A standardized procedure for fabricating an in-shoe shim was utilized for ICHD correction.
resultsThere were no clinically important differences in functional capacity for any subject between any phases. Also, two subjects demonstrated trends towards increased pain over the 12-week experimental period, whereas one subject demonstrated a decrease. One subject demonstrated a statistically significant increase in running distance during intervention phases, but the others demonstrated reductions. All subjects demonstrated trends towards increased running speed, but none were statistically significant.
conclusionThe correction of small ICHD < 9mm did not improve pain or performance among recreational runners. Individuals with small ICHD may be able to effectively compensate for lower extremity asymmetries; therefore, correction seems to be unnecessary and potentially harmful in short-term. LEVEL OF EVIDENCE: Therapy, level 4.
