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

backgroundThe Quadratus Lumborum Block (QLB), which is reported to provide analgesia to the abdominal region, is a newly defined fascial plane block method. The present study aimed to investigate the effect of ultrasound guided anterior QLB on the postoperative pain scores after percutaneous nephrolithotomy.

methodsIn this prospective, randomized, controlled single-blind study, 60 patients with elective percutaneous nephrolithotomy operations were randomized into 2 groups. In Group B (n = 30): anterior QLB+ intravenous patient-controlled analgesia (PCA) morphine and in Group C (n = 30): intravenous PCA morphine. Outcome measures were included for visual analog scale (VAS) scores and morphine consumption for 24 hours postoperatively. Adverse effects, additional analgesic requirement, and intraoperative opioid requirement were recorded.

resultsThe mean values of the quantity of morphine used at the 6th, 12th, and 24th hours were found to be statistically significantly lower in Group B (p < 0.05). The VAS scores were found to be statistically significantly lower in Group B (p < 0.05). There were no statistically significant differences in the rate of adverse effects, additional analgesic requirement, and intraoperative opioid requirement between the groups (p > 0.05).

conclusionThe study results suggest that anterior QLB is an effective treatment option for postoperative analgesia of percutaneous nephrolithotomy.
