Clinical study of ultrasound-guided transversus abdominis plane block for analgesia after cesarean section.
Trial report in Medicine, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPatient-controlled intravenous analgesia (PCIA) and patient-controlled epidural analgesia are 2 common methods of maintaining analgesia after cesarean section. In recent years, transversus abdominis plane block (TAPB) has been gradually applied clinically to reduce opioid analgesics and has achieved good results. Therefore, we performed this study to compare the efficacy and side effects of TAPB and PCIA in analgesia after cesarean section.
methodsOne hundred patients who underwent cesarean section were randomly classified into 2 groups. Following surgery, one group underwent ultrasound-guided TAPB and the other group underwent PCIA. Pain intensity according to the visual analog scale (VAS; 0 for no pain and 10 for severe intolerable pain) was assessed at 2, 4, 6, 8, 12, and 24-hour postsurgery in both groups. The postoperative complication rate and patient satisfaction were also measured.
resultsNo significant differences were found in the VAS scores between the groups (P > .05). However, the incidence of postoperative complications in the TAPB group was significantly lower than that in the PCIA group (P < .05). Furthermore, patient satisfaction in the TAPB group was significantly higher than that in the PCIA group (P < .05).
conclusionThis study demonstrated that ultrasound-guided TAPB can achieve the same analgesic effect as PCIA after cesarean section but with even higher patient satisfaction.
