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

objectiveTo compare the analgesic effects of two types of spinal manipulation (SM) in acute lumbar radiculopathy (ALR) model rats induced by self-transplantation of autologous nucleus pulposus (ANP), and clarify the therapeutic mechanism.

methodsTotally 108 male Sprague-Dawley rats were randomly divided into 6 groups by a random number table (18 rats in each group), including a blank group with no interference, a sham operation group with a surgery by making a local soft tissue incision on the left side of L5-6 vertebral segment, a model group with ALR of L5 extraforaminal nerve by ANP self-transplantation without other interference, a sham manipulation (SMA) group with simulating physical rotation, as well as a mobilization (MOB) group with simulating low-velocity and variable-amplitude rotation and a manipulation (MAN) group with simulating high-velocity and low-amplitude rotation. The interventions in SMA, MOB, and MAN groups started 1 day after modeling followed by another 5 treatments at days 3, 5, 8, 10 and 12. Rats in the other 3 groups did not receive any special intervention. Behavioral pain tests of 50% mechanical pain withdrawal threshold (50% PWT) and paw withdrawal latency (PWL) were conducted 1 day before operation followed by another 10 tests on days 1-7, 10, 12 and 14. Immunohistochemical expression of nitric oxide synthase (NOS) was investigated on days 5 and 12 after operation.

resultsAfter 3 experimental SM interventions, 50% PWT and PWL were higher in the MAN group than the SMA group on days 6 and 7, and higher on days 10, 12 and 14 postoperatively (P<0.05 or P<0.01), while the same indices were significantly higher in the MOB group than MAN group on days 1-4 (P<0.05 or P<0.01). The expression of NOS was lower in the MAN and MOB groups than SMA group on day 12 postoperatively (P<0.01).

conclusionsBoth manipulation and mobilization produced better results than sham interference in relieving pain by reducing neuroinflammation possibly. At the early period, compared with manipulation, mobilization presented less sensitive response to pain until later visit. SM may inhibit the overexpression of NOS, thereby alleviating severe radiculopathy.
