1 · What the graph read from 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.

2 · The registry

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

purposeTo clarify the relationship between early postoperative recovery of mobility and preoperative impairment of the joint position sense in the big toe in patients with lumbar spinal stenosis (LSS).

methodsThe subjects were 247 patients who underwent surgery for LSS. The main outcome was recovery of early postoperative mobility defined as the availability of walking independence after surgery (Barthel index = 15) and the number of days from surgery to starting to walk independently. Preoperative physical functions such as the joint position sense, surgical information and clinical characteristics were measured and analyzed. The relationship between early postoperative recovery of mobility and preoperative impairment of the joint position sense in the big toe was examined using log-rank tests and Cox proportional hazards models.

resultsImpairment of the position sense was observed in 51 patients. Patients with impairment of the position sense had a lower rate of early recovery of mobilization compared with non-impaired patients (63% vs. 89%, p < 0.01). According to the Kaplan-Meier curves, patients with impairment of the position sense had a significant delay in mobilization compared with those who were not impaired (p < 0.01). The hazard ratio for delayed recovery of mobility was 0.54 (95% confidence interval 0.36-0.79).

conclusionPreoperative impairment of the joint position sense in the big toe was a risk factor for prolonged recovery of mobility in the early postoperative period in patients after LSS surgery.
