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

backgroundMany approaches have been reported to repair soft-tissue defects of the hand using dorsal metacarpal artery flaps. Use of a perforator-based propeller flap from the first intermetacarpal space to the dorsum of the hand has been described. The aim of this study was to confirm the functional anatomy of a first dorsal metacarpal artery (FDMA) perforator flap.

methodsTwenty-nine fixed cadaveric hands were dissected to determine the origin, course, and branches of the FDMA. Clinically, five cases of soft tissue defects of the hand underwent reconstructive surgery using an FDMA perforator-based propeller flap.

resultsThe FDMA was found in 27 specimens (93%). The ulnar branch of the FDMA always supplied the cutaneous perforator (mean ± SD, 4.3 ± 1.6), and the most distal cutaneous perforating branch was found along the metacarpal long axis within 25 mm of the tip of the metacarpal head with high frequency (28/29, 97%). In the two hands that had aplasia of the FDMA, well-developed perforators arose directly from the radial artery and advanced to the metacarpal head. Seven hands (24%) had perforators arising from the palmar arterial system, penetrating through or passing close by the second metacarpal bone. In clinical application, all the flaps survived completely without major complications.

conclusionsThe FDMA perforator-based propeller flap is minimally invasive and technically simple. It is expected to be a new option for hand reconstruction.
