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
Tarsal tunnel syndrome is an entrapment neuropathy at the tarsal tunnel. The diagnosis and the prediction of the surgical outcome are difficult. We compared preoperative magnetic resonance imaging findings with the postoperative results. We examined preoperative magnetic resonance imaging findings in 38 consecutive patients with Tarsal tunnel syndrome (47 feet); their mean age was 73.8 years. We inspected the nerve width on the slice showing the most compressed nerve, and the hyperintensity of that nerve on preoperative T2* fat-suppressed axial magnetic resonance imaging images and examined the role of magnetic resonance imaging in the diagnosis and of the surgical outcomes in patients with Tarsal tunnel syndrome. Postoperatively, there was significant symptom improvement. On preoperative magnetic resonance imaging scans the mean width of the most compressed nerve was 0.99 ± 0.37 mm. There was no significant correlation between the preoperative symptom severity and postoperative symptom improvement. In 29 feet (61.7%) we observed hyperintensity of the compressed nerve. In all but one foot the hyperintense area was displayed on 3 axial slices adjacent to the strongest nerve compression point. There was no significant difference in the preoperative symptom severity in patients with (group 1, n = 29) or without hyperintensity (group 2, n = 18). The nerve width at the point of greatest compression was significantly thinner, and postoperative symptom improvement was significantly greater in group 1 patients. Although there was no correlation between the preoperative nerve compression severity and the surgical results, nerve hyperintensity on magnetic resonance imaging scans may help with the diagnosis of Tarsal tunnel syndrome.
