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

aimTo compare using propensity score analysis the outcome of beginning insulin therapy with basal, premix, mealtime + basal or mealtime insulin on the basis of data from 3031 people from the observational CREDIT (Cardiovascular Risk Evaluation in People with Type 2 Diabetes on Insulin Therapy) study. This approach overcomes likely confounding in baseline and unknown characteristics common to observational studies.

methodsEfficacy and safety outcomes were collected at baseline and at 1 year in previously insulin-naïve people. Propensity score matched groups using all available baseline data were defined to compare outcomes by pairs of insulin regimens.

resultsFrom 2659 people with available data, propensity score matches were achieved for 686 people starting premix or basal insulin, 542 starting basal + mealtime or premix insulin and 400 starting basal or basal + mealtime. HbA1c reduction did not differ between the three pairs of insulin regimens. However, the relative risk of overall and nocturnal hypoglycaemia was lower (p = 0.010 to p < 0.001) with basal or basal + mealtime compared with premix insulin, and for nocturnal (p = 0.021) but not overall hypoglycaemia for basal compared to basal + mealtime insulin. Body weight increase was less for basal versus premix insulin [-1.3 (95% CI -2.1, -0.6) kg, p < 0.001] or versus basal + mealtime insulin [-1.4 (-2.5, -0.3) kg, p = 0.016], but did not differ between basal + mealtime and premix. Smaller groups matching mealtime insulin had some residual mismatching of HbA1c.

conclusionComparing insulin regimens between individuals matched by propensity scores indicated differences in hypoglycaemia and body weight change, despite similar HbA1c reductions. Our findings are consistent with those from randomized controlled trials.
