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

To investigate the clinical significance of results in electrodiagnostic evaluations for carpal tunnel syndrome(CTS) and analyze the correlation between electrodiagnostic evaluations and physical examinations, 236 CTS patients and 96 healthy volunteers accepted electrodiagnostic evaluations. There were significant differences between CTS and control groups, mild and moderate patients, moderate and severe patients in CTS groups respectively, in terms of compound muscle action potential(CMAP), sensory conduction velocity of middle finger(SCV), distal motor latency(DML) difference between median nerve and ulnar nerve on the ring finger(△DML) (p < 0.05).△DML has larger area under curve of ROC curve (0.974) than CMAP, SCV and DML(0.748, 0.950, 0.958), then △DML could be included as valuable test for diagnosing and classification of carpal tunnel syndromes. There was low correlation between electrodiagnostic evaluations and physical examinations (rho < 0.4), so electrodiagnostic evaluation and physical examination should be combined to diagnose CTS. TYPE OF STUDY/LEVEL OF EVIDENCE: Diagnostic III.
