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.

Abstract

objectiveThe present study compared the postoperative analgesic effects of femoral triangle block (FTB) with adductor canal block (ACB) in patients undergoing total knee arthroplasty (TKA).

methodsRandomized controlled trials (RCTs) involving the analgesic effects of FTB and ACB post-TKA were collected by searching PubMed, Embase, Web of Science, Cochrane Library, Wanfang, CNKI, and VIP databases from inception till March 2024. The primary outcomes of the study focused on pain scores in resting and activity states, and the secondary outcomes examined the quadriceps muscle strength, postoperative adverse reaction incidence rate, and patient satisfaction scores.

resultsSix RCTs published between 2020 and 2023 were included, which involved altogether 452 patients, with 226 each in the FTB and ACB groups. No significant difference was observed in the resting and activity pain scores at 6, 12, and 24 h between the FTB and ACB groups (P > 0.05). In contrast, at 48 h, the ACB group exhibited better activity pain scores than those in the FTB group (P < 0.05). Three studies concluded that ACB could preserve quadriceps muscle strength, whereas one study concluded that FTB had an advantage in quadriceps muscle strength recovery. Postoperative patient satisfaction scores and adverse reaction incidence rates were not significantly different between the FTB and the ACB groups (P > 0.05).

conclusionThe ACB group demonstrated a certain advantage over the FTB group in the immediate postoperative quadriceps muscle strength recovery. The FTB group showed a better analgesic effect at 48 h than the ACB group. No significant differences were observed in the postoperative adverse reaction incidence rates and patient satisfaction scores between the two groups. Nonetheless, because of the differences in the enrolled articles, further large-scale, high-quality RCTs should be conducted to verify whether ACB is more effective and safer than FTB.
