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

AIMS/

introductionThe aim of the present study was to identify the extent of small fiber neuropathy in diabetic patients with Charcot neuroarthropathy (CN). MATERIALS AND

methodsA total of 20 patients with CN were compared with 20 age- and diabetes duration-matched patients with type 2 diabetes and 20 age-matched control participants. All patients underwent corneal confocal microscopy with quantification of corneal nerve morphology and assessment for vibration perception threshold, and a subset of patients with CN underwent assessment of sudomotor function and neuropathic pain.

resultsIn patients with CN compared with type 2 diabetes patients and control participants, there was a significant reduction in corneal nerve fiber density (14.94 ± 8.23 vs 23.86 ± 7.71, P = 0.004 vs 34.84 ± 9.13, P < 0.001), corneal nerve branch density (18.61 ± 16.7 vs 41.62 ± 22.67, P = 0.032 vs 76.47 ± 38.44, P < 0.001) and corneal nerve fiber length (8.40 ± 4.83 vs 14.87 ± 4.76, P = 0.001 vs 21.24 ± 6.48, P < 0.001), electrochemical skin conductance on the feet (20.57 ± 13.99 vs 61.50 ± 22.26, P < 0.001 vs 76.23 ± 12.01, P < 0.001) and hands (30.86 ± 18.10 vs 61.13 ± 19.14, P = 0.001 vs 68.31 ± 11.96, P < 0.001), and a significant increase in the vibration perception threshold in the feet (38.46 ± 15.10 vs 14.15 ± 10.25, P < 0.001 vs 7.75 ± 4.01, P < 0.001).

conclusionsPatients with diabetes and CN have severe large and particularly small fiber neuropathy.
