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 assess differences in safety and efficacy between 24 and 18 Fr pneumatic balloon dilators for percutaneous nephrolithotripsy (PCNL) of renal stones between 10 and 20 mm.

methodsPatients were randomized to dilatation with a 24 Fr (Group A) versus 18 Fr (Group B) Ultraxx pneumatic dilator (Cook Medical

results42 and 44 patients were assigned to Groups A and B, respectively. Preoperative features were comparable. Mean stone size was 17.8 vs. 16.6 mm in Group A vs. B (p = 0.21). SFR was 95.2% in Group A and 95.4% in Group B (p = 0.19). Postoperative gross haematuria was observed in 5 vs. 2 cases in Group A vs. B (p = 0.04). Mean haemoglobin drop at first postoperative day (POD) was higher in Group A (2.4 vs. 1.1 mg/dl, p = 0.04), while comparable at third POD. Blood transfusion was required in 2 cases in Group A and 1 case in Group B. No patients required embolization. No significant difference was observed in terms of postoperative pain and urinary infection.

conclusions24 and 18 Fr pneumatic dilators are both effective to access renal cavity during PCNL for the treatment of renal stones between 10 and 20 mm. Gross haematuria rate and mean haemoglobin decrease at first POD were significantly higher with 24 Fr dilator, but with no differences in the need for blood transfusions and renal embolization.
