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

purposeTo perform an in-vitro study of the deflection ability of three different Flexible and Navigable Suction Ureteral Access Sheaths (FANS) of two sizes each, and to compare two 7.5Fr single-use ureteroscopes in combination with different FANS under in-vitro conditions.

methodsWe studied two types of 7.5Fr single-use ureteroscopes: the Innovex Medical 7.5Fr single-use Flexible Ureterorenoscope and the Pusen Medical 7.5Fr U-Scope PRO. The six FANS used were the 10/12Fr and 11/13Fr Innovex 40 cm FANS, ClearPetra 46 cm FANS, and Reborn 40 cm FANS. Deflection angles of the ureteroscopes were measured under four different working channel conditions: empty working channel, with a 150 μm and 200 μm SOLTIVE Thulium fiber laser, and 1.9Fr Zero-Tip Nitinol Basket.

resultsThe Innovex ureteroscope had greater angles of deflection compared to the Pusen ureteroscope in all four different working channel conditions without FANS, but this was only statistically significant with an empty working channel (p = 0.02) and 200 μm fiber laser (p = 0.05). All three 10/12Fr FANS had greater deflection angles than their 11/13Fr counterparts but this was not statistically significant. When deflecting all six FANS across all working channel conditions, the Innovex ureteroscope had greater angles of deflection compared to the Pusen ureteroscope, but this was not statistically significant. The Innovex FANS showed the greatest deflection ability, followed by the ClearPetra FANS, with the Reborn FANS having the least deflection ability for both 10/12Fr and 11/13Fr FANS.

conclusions7.5Fr flexible ureteroscopes deflected FANS better when used with a 10/12Fr FANS rather than a 11/13Fr FANS. The Innovex and ClearPetra FANS performed similarly well in their deflection ability.
