Comparison of single-injection ultrasound-guided thoracic paravertebral block with transversus abdominis plane block in peritoneal dialysis catheter implantation: a randomized controlled trial.
Trial report in Trials, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundPrevious study indicated that transversus abdominis plane (TAP) block could be the principal anesthetic technique for peritoneal dialysis catheter (PDC) implantations. However, a TAP block could not provide an optimal anesthetic effect on catheter exit site during PDC implantation. We hypothesized that single-injection ultrasound-guided thoracic paravertebral block (US-TPVB) could be the principal anesthetic technique with better pain relief at catheter exit site during PDC implantation, compared to a TAP block. And anesthesia quality of a single-injection US-TPVB was compared with that of a TAP block and local anesthetic infiltration (LAI).
methodsPatients undergoing PDC implantations were randomized into groups TPVB or TAP or LAI. In group TPVB, single-injection US-TPVB at T10-T11 level was performed with 20 ml of 0.25% ropivacaine. In group TAP, oblique subcostal TAP block was performed with 20 ml of 0.25% ropivacaine. In group LAI, 40 ml of 0.25% ropivacaine was used. Anesthesia quality was compared among the three groups, including general anesthesia conversion rate, cumulative rescuing sufentanil consumption, and satisfaction rate by nephrologists and patients.
resultsEighty-eight eligible patients were enrolled. Visual analogue scale (VAS) at most time points (except for the catheter exit site) were lower in group TAP, compared with group TPVB. VAS at parietal peritoneum manipulation was 6 (5, 7), 3 (0, 6), and 7 (4.75, 9) in groups TPVB, TAP, and LAI, respectively (P < 0.001). VAS at catheter exit site was 4 (3, 4), 5.5 (4, 8), and 5 (3, 7.25) in groups TPVB, TAP, and LAI, respectively (P = 0.005). Lower general anesthesia conversion rate, less cumulative rescuing sufentanil consumption, and higher satisfaction rates by nephrologists and patients were recorded in group TAP, compared with groups TPVB and LAI.
conclusionsSingle-injection US-TPVB provided a better pain relief at catheter exit site. The quality and reliability of anesthesia after a single-injection US-TPVB was comparable to that of LAI, but not better than that of an oblique subcostal TAP block for PDC implantation.
