The Oswestry Disability Index and 12-Item Short Form Health Survey Physical Component Scores Are Not Affected by Recall Bias in Posterior Lumbar Spine Surgery Patients: A Prospective Study Using Data From Fitness Trackers.

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
objectiveTo assess the effects of recall bias on prospectively collected patient-reported outcome (PRO) measures after lumbar laminectomy by analyzing correlations between PROs and step counts in measurement windows preceding PRO measurement.
methodsResponses to the 12-item Short Form Health Survey (SF-12) and the Oswestry Disability Index (ODI) were collected postoperatively from 22 patients. Accelerometers recorded daily step counts. Median and maximum step counts were calculated for windows (1 day, 3 days, 1 week, and 2 weeks) preceding PRO measurement. Spearman rank correlation coefficients between PROs and step counts were calculated.
resultsMedian and maximum step counts from 1- and 2-week windows more consistently correlated with SF-12 Physical Component Scores scores than 1- and 3-day windows over the postoperative period. Median steps from 1-, 2-week, and 3-day windows correlated more with ODI scores than the 1-day window. Maximum steps from 1- and 2-week windows correlated more than 1- and 3-day windows. DISCUSSION: PROs had higher concordance with step counts from the 1 week and 2 weeks before PRO measurement than the 1 day and 3 days prior. We therefore conclude that SF-12 and ODI are not markedly affected by recall bias because scores are not skewed by the events of the days immediately preceding measurement.
