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

STUDY

designProspective, observational cohort study.

objectiveSelective nerve root block (SNRB) is an effective, standard interventional procedure for failed medical management in lumbar disc herniation (LDH). However, the factors that would predict successful outcomes in patients undergoing SNRB have not been clearly studied.

methodsPatients with failed conservative treatment for acute LDH, treated with SNRB were periodically followed till 1 year. Patients who failed to have pain relief or had recurrent pain after SNRB, underwent surgery. The pattern of radiculogram during SNRB was classified into 4 types-"arm," "arrow," "linear," and "splash." Various clinical factors, radiological factors, and radiculograms were compared between patients who had consistent pain relief (group A) and those patients who did not (group B).

resultsA total of 91 patients underwent SNRB. Sixty-nine had good pain relief maintained till 1 year (75.8% success). Twenty-two patients underwent surgery after failed NRB at a mean of 6.3 weeks. Patients with sensory symptoms (

conclusionsSNRB is an effective technique to provide consistent symptom relief at least till 1 year in patients with acute LDH. The study identified several factors that predicted poor outcomes of SNRB and such patients can be forewarned about need for later surgery.
