Pre-emptive analgesia with methylprednisolone and gabapentin in total knee arthroplasty in the elderly.
Trial report in Scientific reports, 2022. 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
The aim of this study is to assess whether administration of gabapentin and methylprednisolone as "pre-emptive analgesia" in a group of patients above 65 years of age would be effective in complex pain management therapy following total knee arthroplasty (TKA). One hundred seventy patients above 65 years were qualified for the study, with exclusion of 10 patients due to clinical circumstances. One hundred sixty patients were randomly double-blinded into two groups: the study group (80 patients) and the control group (80 patients). The study group received as "pre-emptive" analgesia a single dose of 300 mg oral (PO) gabapentin and 125 mg intravenous (IV) methylprednisolone, while the control received a placebo. All patients received opioid and non-opioid analgesic agents perioperatively calculated for 1 kg of total body weight. We measured (1) pain intensity level at rest (numerical rating scale, NRS), (2) life parameters, (3) levels of inflammatory markers (leukocytosis, C reactive protein CRP), and (4) all complications. Following administration of gabapentin and methylprednisolone as "pre-emptive" analgesia, the NRS score at rest was calculated at 6, 12 (p < 0.000001), 18 (p < 0.00004) and 24 (p = 0.005569) h postoperatively. Methylprednisolone with gabapentin significantly decreased the dose of parenteral opioid preparations (p = 0.000006). The duration time of analgesia was significantly longer in study group (p < 0.000001), with CRP values lower on all postoperative days (1, 2 days-p < 0.00001, 3 days-p = 0.00538), and leukocytosis on day 2 (p < 0.0086) and 3 (p < 0.00042). No infectious complications were observed in the first postoperative days; in the control group, one patient manifested transient ischemic attack (TIA). The use of gabapentin and methylprednisolone as a single dose decreased the level of postoperative pain on the day of surgery, the dose of opioid analgesic preparations, and the level of inflammatory parameters without infectious processes.
