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
backgroundEffects of preoperative continuous regional block on perioperative analgesia and postoperative recovery in hip fracture patients remain to be determined. This randomized trial was designed to investigate the impact of preoperative continuous supra-inguinal fascia iliaca block (FIB) or anterior quadratus lumborum block (QLB) on quality of recovery after hip fracture surgery.
methodsEligible patients were randomized to receive preoperative continuous supra-inguinal FIB, continuous anterior QLB, or conventional analgesia (no block; control group). Preoperative continuous regional blocks were initiated at hospital admission and induced with 40 ml of 0.375% ropivacaine and maintained with 5 ml/h of 0.2% ropivacaine, and reinforced with 30 ml of 0.375% ropivacaine before surgery. The primary endpoint was quality of recovery (QoR) assessed with the QoR-40 questionnaire at 24 h after surgery. Secondary endpoints included pain intensity before and after surgery.
resultsA total of 159 patients were randomized, with 53 patients in each group. The QoR-40 score at 24 h was median 184 [IQR 176 to 187] in the control group, 185 [178 to 191] with supra-inguinal FIB, and 188 [182 to 191] with anterior QLB (P = 0.042), respectively; the QoR-40 score was higher in the anterior QLB group than in the control group (median difference 4; 95% CI 1 to 7; P = 0.008) although this difference was not clinically important. Both regional blocks alleviated pain intensity before surgery, but only anterior QLB provided better analgesia for up to 72 postoperative hours.
conclusionsPreoperative continuous anterior QLB improved perioperative analgesia and was associated with a slightly better early postoperative recovery whereas continuous supra-inguinal FIB did not.
