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

introductionAccording to current clinical practice, a minimum of 7 knots are required to provide secure hold in high-strength sutures. A new technology featuring a suture tape with a salt-infused silicon core has been recently developed, potentially reducing the number of needed knots.

aimsto (1) assess the influence of number of knots on tape security, (2) evaluate the effect of different ambient conditions on knot security, and (3) compare the biomechanical competence of the novel versus a conventional suture tape. MATERIALS AND

methodsA conventional suture tape (ST, SutureTape

resultsWhereas the ST ruptured without unraveling with a minimum of 6 knots in all specimens and ambient conditions, the minimum number of knots for a DT rupture without unraveling was 6 in dry, 4 in wet, and 5 in fatty-wet condition. Ultimate force at rupture with a minimum number of needed knots did not differ significantly between ST and DT (p ≥ 0.067), in contrast to knot slippage that was significantly bigger for ST versus DT in wet and fatty-wet conditions(p ≤ 0.001).
