Posterior transversus abdominis plane block versus lateral quadratus lumborum block in children undergoing open orchiopexy: a randomized clinical trial☆.
Trial report in Brazilian journal of anesthesiology (Elsevier). The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to 2 registered trials, which are not on this map. Cited by 5 papers, 1 of them a synthesis that pooled 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.
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.

Abstract
backgroundDue to the complex innervation of the testicle and spermatic cord, analgesic management can be challenging in orchiopexy. We aimed to compare the effects of posterior Transversus Abdominis Plane (TAP) and lateral Quadratus Lumborum Block (QLB) on analgesic use, pain, and parent satisfaction in unilateral orchiopexy.
methodsASA I-III, aged 6 months -to 12 years children undergoing unilateral orchiopexy were included to this double-blinded randomized trial. Patients were randomized into two groups with the closed envelope method before the surgery. Lateral QLB or posterior TAP block was applied under ultrasonography with 0.4 ml.kg
resultsA total of 90 patients were included in the analysis (45 patients in each group). The number of patients needing remifentanil was significantly higher in the TAP group (p < 0.001). The average FLACC (TAP: 2.74 ± 1.8, QLB: 0.7 ± 0.84) and Wong-Baker scores (TAP: 3.13 ± 2.42, QLB: 0.53 ± 1.12) were significantly higher for TAP (p < 0.001). Additional analgesic consumption at the 10
conclusionLateral QLB provided more effective analgesia than posterior TAP block in children undergoing elective open unilateral orchiopexy. CLINICAL TRIALS REGISTRY: NCT03969316.
