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.

2 · The registry

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

unlabelledWe evaluated the effect of infiltration of dilute solutions of capsaicin, administered before plantar incision, on 3 pain-related behaviors: guarding pain, heat-withdrawal latency, and mechanical-withdrawal threshold. Perineural application of capsaicin was also studied and the appearance of the wound was also evaluated. Dilute solutions of capsaicin .025% and .10% were infiltrated in the plantar region 1 day before incision. In another group of rats, perineural capsaicin (1%) was applied to the nerves innervating the plantar aspect of the rat hindpaw. Rats were then tested for pain-related behaviors before and after plantar incision and then daily thereafter. Wound appearance was graded and histopathology was evaluated. Infiltration with capsaicin reduced guarding pain and heat hyperalgesia after plantar incision; there were minimal effects on mechanical responses. Perineural-capsaicin application produced a similar result. Both capsaicin infiltration and perineural-capsaicin application impaired wound apposition. Histologic evaluation also confirmed impaired wound apposition after capsaicin infiltration. In conclusion, dilute solutions of capsaicin have differential effects on pain-related behaviors after plantar incision. Based on the antinociception produced by capsaicin both via infiltration and perineural injection, the effect on wound appearance was likely related to its inhibitory effects on pain behaviors and was not necessarily a local effect of the drug. PERSPECTIVE: This study demonstrated that capsaicin infiltration before plantar incision produced an analgesic effect that depended upon the stimulus modality tested. When evaluating novel treatments for postoperative pain, studies using a single stimulus modality may overlook an analgesic effect by not examining a variety of stimuli.
