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

backgroundSome publications have recently been released on the safety of non-papillary access (NPA) in percutaneous nephrolithotomy (PCNL) by a Greek group. The purpose of this study was to prospectively examine the outcome of NPA during two years in a referral center.

methodsThis prospective cohort study was conducted on PCNL operations performed from January 2020 to April 2022 in Labbafinejad Hospital. In cases in which obtaining papillary access (PA) was not obtainable after several attempts and NPA was obtained, or in cases in whom after entry to the pyelocalyceal system, a NPA was observed, the cases were categorized in the NPA group (n = 67). The control group (PA) was composed of patients who had undergone PCNL with papillary access with similar stone bulk (n = 67). The primary endpoints of interest were hemoglobin drop and transfusion frequency. The secondary endpoint included: stone free rate (SFR), operation duration, and complications.

resultsA total of 134 patients were enrolled during the study period which included 33 female patients (25%). The mean ± SD age of patients was 49.6 ± 13.2 years. The frequency of transfusion and residual stones was not different between NPA and PA groups: 6 (9%) versus 8 (11%), P = 0.29; and 16 (24%) versus 12 (18%), P = 0.26. Likewise, the operation time (87.6 ± 25.8 versus 90.2 ± 22.6 min, P = 0.45), and the frequency of intraoperative and postoperative complications were not different between the NPA and PA groups.

conclusionThe results of this prospective study did not reveal a higher frequency of residual stones, transfusion, or complications in the NPA group. Nevertheless, our study is not powered enough to reveal complications of low frequency including delayed bleeding.
