Does task shifting in tuberculosis microscopy services to non-certified technicians in Afghanistan affect quality?
Article in Public health action, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
settingTuberculosis microscopy centres in 30 provinces in Afghanistan.
objectiveTo compare the quality of sputum smear examinations in microscopy centres with microscopists who are fully certified as laboratory technicians with those performed in centres with technicians who do not have such certification (high school graduates).
designCross-sectional record review of sputum smear microscopy slides examined by technicians and cross-checked by trained assessors as part of routine external quality assurance between July and September 2009.
resultsOf 129 non-certified technicians, 118 (91%) were stationed in rural health centres compared with 217/257 (84%) certified technicians. From 386 microscopy centres, 7313 slides were cross-checked. Of 257 microscopy centres with certified technicians, 42 (16%) had at least one slide with a major error compared to 23 (18%) of 129 microscopy centres staffed with non-certified technicians. The difference was not statistically significant (OR 1.11, 95%CI 0.64-1.94). The number of slides showing major errors was also similar between the centres with both certified and non-certified technicians.
conclusionThis study confirms the deployment of non-certified microscopy technicians to peripheral health centres throughout the country and that their performance with sputum smear microscopy is similar to that of certified technicians with 3 years of training.
