Response rate does not affect patient-reported outcome after lumbar discectomy.

The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 33 papers, 2 of them syntheses that pooled it.
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
purposeQuality registers give unique possibilities to achieve information from large groups of patients, but outcome must be interpreted carefully due to less stringent data collection and lower follow-up rates than in research projects. We tried to quantify any outcome differences between a national spine quality register and a prospective observational study.
methodsAdult patients treated with lumbar discectomy between 2004 and 2010 were retrieved from the Swedish Spine register (Swespine) (n = 7791) and from the single center lumbar disc herniation study (LDHS) in Stockholm (n = 177). The mean follow-up rates at 1 and 2 years were 73 and 62%, compared to 98 and 99%, respectively. Patient-reported outcome measurements included VAS for back and leg pain, ODI, EQ-5D, patient satisfaction, and global assessment.
resultsWhen comparing the two cohorts at baseline, there were minor differences in the patient-reported outcome measurements, all within reported minimal clinical important differences (MCID). Mean outcome improved significantly in both groups after surgery. All outcomes at 1 and 2 years were similar and within the reported MCID in both groups. Complications and reoperations were similar, except for more surgical site infections in the LDHS group.
conclusionsHigher response rates than seen in Swespine are not needed to achieve reasonably representative data on patient-reported outcome for large cohorts. Two-year data do not seem to add additional information. These slides can be retrieved under Electronic Supplementary Material.
